Using high and low-temperature impact test chambers will have an immeasurable impact on building a resource-efficient society.
5. Excellent Anti-corrosion Performance: When exposed to air at high temperatures, alloy cables immediately form a dense oxide layer that is highly resistant to various forms of corrosion, making them suitable for harsh environments. Additionally, the optimized internal structure of the alloy conductor and the use of silane cross-linked polyethylene insulation material extend the service life of alloy cables by more than 10 years compared to copper cables.                      

When the Guangdong Hongzhan ice water impact test chamber is used in summer, the following matters should be paid special attention to to ensure the stable operation of the equipment and the accuracy of the test results:

1. Environment and heat dissipation management

  Enhance ventilation and heat dissipation High temperature in summer is easy to lead to the decrease of equipment heat dissipation efficiency. Ensure that at least 10cm space is reserved around the equipment to promote air circulation. If the equipment adopts air cooling system, the condenser surface dust should be cleaned regularly to prevent poor heat dissipation and overheating of the compressor.Control the environmental temperature and humidity. Avoid placing the equipment in the direct sunlight area. It is recommended that the laboratory temperature be kept at 25±5℃ and the humidity be lower than 85%. High temperature and high humidity environment may accelerate the accumulation of frost or condensation water on the equipment, so it is necessary to increase the dehumidification measures.

2. Refrigeration system maintenance

  Water quality and tank management Bacteria are easy to breed in summer, so use deionized water or pure water to avoid hard water scaling and blocking pipes. It is recommended to change the tank water every 3 days, and empty and clean the tank before long-term disuse.Refrigeration efficiency monitoring High temperature environment may lead to overload operation of the refrigeration system. The compressor oil condition should be checked regularly to ensure sufficient refrigerant. If the water temperature exceeds the set value (such as 0~4℃), the machine should be stopped immediately for troubleshooting.

3. Frosting and defrosting treatment

  Prevent frost aggravation When the humidity is high in summer, the frost rate inside the equipment may accelerate. It is recommended to perform a manual defrosting process after 10 cycles: set the temperature to 30℃ and keep it for 30 minutes, and then drain water to clean the ice crystals on the evaporator surface.

Optimize the test interval to avoid continuous long-term low temperature testing. It is recommended to reserve 15 minutes of buffer time between high temperature (e.g., 160℃) and ice water shock cycle to reduce the impact of thermal stress on the equipment.

4. Adjustment of operation specifications

  Parameter setting optimization According to the characteristics of the summer environment, the normal temperature recovery stage time can be shortened appropriately (the reference standard is to complete the temperature switch within 20 seconds), but it must ensure that it meets the requirements of GB/T 2423.1 or ISO16750-4 standards.Safety protection should be strengthened. Anti-freezing gloves and goggles should be worn during operation to avoid the adhesion of hands and low-temperature parts caused by sweating. Before opening the door after high temperature test, the temperature inside the box should be confirmed to be below 50℃ to prevent scalding from hot steam.

5. Emergency and long-term shutdown preparation

  Fault response If the equipment has E01 (temperature out of tolerance) or E02 (water level abnormal) alarm, you should immediately cut off the power supply and contact the technical support of the manufacturer. Do not disassemble the refrigeration pipeline by yourself.Long-term protection When not used for more than 7 days, the water tank should be emptied, power should be cut off and dust cover should be covered. At the same time, power should be on for 1 hour every half a month to keep the circuit board dry.

  Through the above measures, the impact of high temperature and humidity environment in summer on the ice water shock test chamber can be effectively reduced to ensure the reliability of test data and the service life of the equipment. The specific operation details should be adjusted according to the equipment manual and actual working conditions.

High and low temperature test chamber may encounter a variety of problems in the process of use, the following is a summary of potential faults and their causes from different perspectives:

1. Core system failure

Reason: PID control parameters are out of balance, ambient temperature exceeds the design range of the equipment, multi-zone temperature interference.

Case: In a special environment workshop, the external high temperature causes the refrigeration system to overload, resulting in temperature drift.

Humidity is abnormal

Reason: poor water quality of humidification leads to scaling and nozzle blockage, failure of ultrasonic humidifier piezoelectric sheet, and incomplete regeneration of dehumidification desiccant.

Special phenomenon: reverse condensation occurs during high humidity test, resulting in the actual humidity in the box being lower than the set value.

2. Mechanical and structural problems

Air flow is disorganized

Performance: There is a temperature gradient of more than 3℃ in the sample area.

Root cause: the customized sample rack changed the original design air duct and the accumulation of dirt on the centrifugal fan blade led to the destruction of dynamic balance.

 sealing failure

New failure: the magnetic force of electromagnetic sealing door decreases at low temperature, and the silicone sealing strip becomes brittle and cracks after-70℃.

3. Electrical and control system

Intelligent control failure

Software level: After firmware upgrade, the temperature dead zone setting error occurs and the historical data overflow causes the program to crash.

Hardware level: SSR solid state relay breakdown causes continuous heating and bus communication is subjected to inverter electromagnetic interference.

Security protection vulnerabilities

Hidden dangers: the synchronous failure of the triple temperature protection relay and the false alarm caused by the expiration of the refrigerant detector calibration.

4. Challenges of special working conditions

Specific temperature shock

Problem: -40℃ to +150℃ rapid conversion of the evaporator weld stress cracking, thermal expansion coefficient difference resulting in the failure of the observation window seal.

Long-term operation attenuation

Performance degradation: after 2000 hours of continuous operation, the compressor valve plate wear leads to a decrease of 15% in refrigeration capacity and drift of ceramic heating tube resistance value.

5. Environmental and maintenance impact

Infrastructure adaptation

Case: The power oscillation of PTC heater caused by the fluctuation of power supply voltage and the water hammer effect of cooling water system damaged the plate heat exchanger.

Preventive maintenance blind spots

Lesson: Ignoring the positive pressure of the box leads to water entering the bearing chamber and biofilm growth and blockage in the condensate discharge pipe.

6. Pain points of emerging technologies

New refrigerant application

Challenges: system oil compatibility problems after R448A replaces R404A, and high pressure sealing problems of subcritical CO₂ refrigeration systems.

IoT integration risks

Fault: The remote control protocol is maliciously attacked, resulting in program tampering and cloud storage failure, resulting in the loss of test evidence chain.

Strategy recommendations

Intelligent diagnosis: configure vibration analyzer to predict the failure of compressor bearing, and use infrared thermal imager to scan the electrical connection points regularly.

Reliability design: key components such as evaporator are made of SUS316L stainless steel to improve corrosion resistance, and redundant temperature control modules are added to the control system.

Maintenance innovation: implement a dynamic maintenance plan based on operating hours, and establish an annual refrigerant purity testing system。

The solutions to these problems need to be analyzed in combination with the specific model of the equipment, the use environment and the maintenance history. It is recommended to establish a collaborative maintenance mechanism including the OEM of the equipment, third-party testing institutions and user technical teams. For key test items, it is recommended to configure a dual-machine hot standby system to ensure the continuity of testing.

  The Guangdong Hongzhan Dust Test Chamber is primarily used to simulate natural sand and dust environments, testing the dust resistance of various products. In industries such as electronics, automotive, and aerospace, products may face challenges from sand and dust. If a product's dust resistance is inadequate, sand and dust particles can penetrate the equipment, leading to malfunctions, performance degradation, or even damage. Therefore, accurately assessing a product's dust resistance is crucial, and the Guangdong Hongzhan Dust Test Chamber provides a reliable testing platform for companies.

(1) Box structure: combination of robust and durable and sealing

The test chamber is constructed from high-quality stainless steel, which not only provides excellent corrosion resistance and protection against sand and dust erosion but also ensures good sealing to prevent sand and dust leakage, maintaining the stability of the testing environment. The interior is meticulously divided into functional areas such as the sample testing zone, sand and dust circulation duct, heating system, and control system, facilitating both operation and maintenance.

(2) Dust generation system: accurate simulation of dust environment

This is one of the core components of the test chamber. It consists of a sand and dust storage unit, a sand and dust conveying unit, and a sand and dust dispersion unit. The storage unit can hold sand and dust of various sizes and compositions as required by the test. The conveying unit delivers the sand and dust into the test chamber using either a screw conveyor or an air conveying method. The dispersion unit ensures that the conveyed sand and dust is evenly distributed in the air, creating a stable and suitable sand and dust environment for testing, ensuring that each sample is thoroughly tested under uniform conditions.

(3) Air circulation system: create stable dust airflow

The air circulation system consists of a fan, ducts, and an air filter. The fan provides the necessary power to ensure the air circulates within the test chamber. The ducts guide the airflow effectively, ensuring that the air passes through the sand and dust generation system and the sample testing area, allowing the sand and dust to fully contact the samples. The air filter effectively removes sand and dust particles from the circulating air, protecting the fan and other equipment from damage and extending their lifespan.

(4) Control system: intelligent and accurate operation core

The control system employs an advanced programmable logic controller (PLC) and a touch screen interface. Operators can easily set and monitor test parameters, such as temperature, humidity, dust concentration, and wind speed, via the touch screen. It also features automatic adjustment capabilities, allowing it to continuously monitor and precisely adjust the various parameters inside the test chamber according to preset values, ensuring that the testing environment always meets the required standards. Additionally, the control system includes fault alarm and protection functions, which can promptly issue warning signals and take protective measures in case of any abnormal conditions, ensuring the safety of both equipment and personnel.

(5) Complete workflow: efficient and rigorous testing process

  During the preparation phase, operators select appropriate sand and dust particles based on the test requirements and place them in the storage device. They then clean and inspect the test chamber and properly position the samples within the testing area. Once the test chamber is activated, the sand and dust generation system begins to operate, conveying and dispersing the sand and dust into the air. The air circulation system ensures a stable flow of sand and dust air. The control system continuously monitors and adjusts various parameters to maintain a stable test environment. During the sample testing phase, the test chamber operates according to the set schedule

In busy logistics hubs and warehouses, moving goods efficiently is a top priority. One tool that’s become increasingly important in this process is the telescopic belt conveyor. If you've ever seen a long conveyor sliding in and out of a truck like a giant mechanical arm, you've likely seen one in action. But what exactly is it, and how does it actually work?

Let’s break it down in a way that combines technical understanding with real-world application.

A Simple Definition

At its core, a 4 extension loading and unloading conveyor is a kind of conveyor system that can extend and retract, much like a telescope. This movement allows it to reach inside trucks or containers for easier loading and unloading. The design significantly reduces manual handling, improves safety, and speeds up operations.

In more technical terms, it's a multi-section conveyor where the nested sections slide out to extend the length. The belt moves continuously along these sections, even as the conveyor extends or contracts.

How Does It Work?

Now let’s get into the mechanics—without sounding like a textbook.

Imagine you’ve got a truck backed up to your dock. Instead of sending in workers to carry boxes one by one, you roll up the telescopic conveyor. At the press of a button (or using manual control in simpler models), the conveyor slides forward, reaching deep inside the truck.

The moving belt—usually made from durable rubber or PVC—carries boxes from the vehicle right into the warehouse or the other way around. Some models even let you adjust the height or tilt the conveyor to match different truck sizes or dock levels.

And when the job’s done? Just retract the conveyor back like a telescope and roll it away. Simple, right?

Key Features (from a Practical Viewpoint)

While tech specs matter, most warehouse managers care more about how it helps:

Adjustable length – So you can handle different truck sizes.

Height control – For aligning with containers or dock heights.

One-person operation – Reduces manpower costs.

Fast belt movement – Speeds up loading and unloading dramatically.

Safety mechanisms – Like emergency stop buttons and anti-slip belts.

Where Is It Used?

You’ll find mobile telescopic belt conveyors in a lot of places:

Logistics centers shipping thousands of parcels daily

Online retail fulfillment hubs (think e-commerce giants)

Courier and express parcel services

Airports, for baggage handling

Warehouses and storage facilities

Basically, if there are goods constantly coming in and going out, a telescopic conveyor makes the job smoother.

Why Are Telescopic Belt Conveyors So Popular?

Now, let’s get real. Time is money—and in logistics, wasted time equals wasted revenue. A conveyor that extends into a truck eliminates time-consuming, back-breaking labor. Not to mention, it cuts down the chance of workplace injuries.

From a formal point of view, telescopic conveyors are recognized as effective solutions for enhancing logistics productivity, operational safety, and space optimization.

And let’s not forget the long-term cost savings. Fewer injuries mean fewer insurance claims. Faster operations mean quicker turnaround. That’s good news for your bottom line.

Whether you’re running a small warehouse or managing a large distribution center, investing in a telescopic belt conveyor can seriously streamline your operations. It's not just a piece of equipment—it’s a way to modernize your entire loading process.

So next time you’re stuck waiting on slow, manual unloading? Just imagine how a telescopic conveyor could slide right in and change everything.

Selecting a suitable tiger shear is crucial for efficient metal recycling and processing. Here are some key factors to consider.

Clarify Your Needs

First, assess the type of materials you'll be shearing. Is it thin - gauge steel, thick metal plates, or various metal alloys? For instance, if you often deal with thick industrial - grade steel, you'll need a shear with high - tonnage capacity. Additionally, consider the volume of work. High - volume operations require a shear that can handle continuous use without frequent breakdowns.

Shearing Capacity

Tiger shears come in different tonnage ratings. The tonnage indicates the maximum force the shear can exert. To determine the right capacity, measure the thickness and hardness of the materials you'll be cutting. A general rule is that harder and thicker materials demand a higher - tonnage shear.

Blade Quality

The blades are the heart of the tiger shear. For regular use with common metals, high - carbon steel blades can be sufficient. However, if you're working with special alloys or very hard metals, invest in blades made of more durable materials, such as alloy steel or even imported blades, which can resist wear and maintain sharpness longer.

Optional Features

Some shears offer features like adjustable shear angles, which can be useful when you need to cut materials at specific angles. Others may have automated feeding systems, reducing labor and improving productivity. Consider whether these features align with your workflow and budget.

By carefully evaluating these aspects, you can choose a tiger shear that meets your needs, boosts productivity, and ensures long - term cost - effectiveness in your metal - processing operations.

Enter the metal briquetting machine: an industrial powerhouse that transforms chaotic waste into dense, manageable briquettes, unlocking efficiency and sustainability.  

 What is a Metal Briquetting Machine?  

A metal briquetting machine uses extreme hydraulic or mechanical pressure to compact loose metal scraps into solid, high-density blocks or "briquettes." Think of it as a giant press that squeezes fistfuls of aluminum spaghetti or steel wool into neat, brick-like units. This process typically involves:  

1.  Feeding: Scrap is loaded into a hopper.  

2.  Compaction: A hydraulic ram exerts force (often 100–3,000+ tons), compressing metal against a rigid mold.  

3.  Ejection: The formed briquette is pushed out, ready for handling.  

 Materials Processed  

These machines handle diverse metals, including:  

- Ferrous: Steel, cast iron, stainless steel turnings.  

- Non-Ferrous: Aluminum, copper, brass, bronze chips.  

- Exotic Alloys: Titanium, nickel-based superalloys (common in aerospace).  

Note: Lubricants/coolants in chips are often expelled during compaction and can be filtered/recycled.  

 Key Benefits: Why Briquetting Matters  

1.  Volume Reduction:  Briquettes occupy up to 90% less space than loose scrap. This slashes storage and transport costs dramatically.  

2.  Value Recovery: Briquettes are "clean metal" with minimal oxidation. Mills and foundries pay 15–30% more for briquettes vs. loose scrap due to ease of melting, reduced slag, and higher yield.  

3.  Safety & Cleanliness: Eliminates slippery, hazardous piles of sharp chips. Reduces fire risks (especially with oily swarf) and improves workshop hygiene.  

4.  Environmental Compliance: Prevents toxic coolant runoff. Lowers carbon footprint via efficient transport and recycling.  

5.  Recycling Efficiency: Briquettes melt faster and more uniformly in furnaces, saving energy (20–30% less energy per ton in remelting).  

 Industries Served  

- Automotive: Machining plants generating tons of aluminum/steel chips.  

- Aerospace: Recycling high-value titanium and Inconel waste.  

- Metal Foundries: Handling returns, gates, and risers.  

- Recycling Centers: Processing mixed scrap streams efficiently.  

 Types of Briquetters  

- Vertical Hydraulic: High-pressure, ideal for tough materials (steel, stainless steel).  

- Horizontal Hydraulic: Easier integration into conveyor systems for high-volume chips.  

- Mechanical (Punch & Die): Faster cycle times for softer metals like aluminum.  

 The Bottom Line  

Metal briquetting machines are more than just compactors — they are profit centers and sustainability engines. By converting waste into a premium commodity, they deliver rapid ROI (often under 2 years) while supporting circular economy goals. In an era where resource efficiency and ESG metrics are paramount, briquetting technology proves that one industry’s trash is truly its own treasure.  

Investing in a briquetter isn't just about managing scrap; it's about reclaiming value, space, and responsibility — one solid briquette at a time.
