In today’s era of pursuing efficient and eco-friendly energy use, the choice of water source is crucial for scroll heat pump units, a key heating and cooling equipment. After comprehensive consideration and practical verification, groundwater is undoubtedly the most ideal water source for these units.

Groundwater boasts stable temperature characteristics. Unlike surface water, which is greatly affected by seasons and climate, groundwater maintains a relatively constant temperature year-round. This is vital for the stable operation of scroll heat pumps. In winter, when surface water temperatures drop sharply, groundwater remains at a suitable level, providing a sufficient and steady heat source for the pump to ensure heating efficiency. In summer, when surface water becomes too warm for cooling, the lower temperature of groundwater helps the unit cool efficiently, reducing energy consumption and boosting overall operational performance.

If you've ever wondered why 18 inch 5 holes forged wheels are so popular, the answer lies in their careful manufacturing process. 

These wheels— a common size for many passenger cars and SUV cars— go through a series of precise steps that guarantee quality, strength, and consistency, traits that make them stand out from mass-produced alternatives.

The process starts with picking the right materials. Most 18 inch 5 holes forged wheels use high-grade aluminum alloys like 6061, chosen for their great strength-to-weight ratio. First, the aluminum block is heated to a specific temperature to make it malleable, then placed in a forging press that uses thousands of tons of pressure to shape it into a rough wheel blank. This step is critical: it gets rid of air bubbles and lines up the metal’s grain, creating a structure far stronger than cast metal.

Next comes heat treatment. The wheel blank goes through solution heat treatment and aging, which strengthens the aluminum by forming tiny precipitates in its microstructure. This ensures the wheel can handle daily driving stresses— from hitting potholes to cornering at high speeds. After heat treatment, the blank moves to machining, where precise tools refine its size, carve out spokes, and drill the 5 bolt holes. Each hole is measured exactly to fit the vehicle's hub perfectly.

The wheel is polished, painted, or powder-coated to boost its appearance and protect it from corrosion. This not only makes 18 inch 5 holes forged wheels look great but also extends their lifespan, keeping them in top condition for years. Quality control checks happen at every stage, from material inspection to final assembly, to catch any defects and maintain high standards.

The result? A wheel that's not just good-looking but also incredibly durable and reliable. 18 inch 5 holes forged wheels earn their reputation from this strict manufacturing process, which combines advanced technology with skilled craftsmanship. For drivers who want both style and performance, these wheels are proof of how much quality manufacturing makes a difference.

Being as packaging machine manufacturer of corrugated industry for more than 20 years, Keshenglong has our own experience and innovate continuously.

On Feb. 26th, 2016, our company GUANGZHOU KESHENGLONG CARTON PACKING MACHINE CO.,LTD. applied for a press-free feeding device of printing machine patent certification.

After more than two years of experts’ approval, SIPO granted the patent to us for 20 years duration.

Since we designed this press-free feeding device, when clients using our cardboard box printing machine, would sincerely feel the convenience, high efficiency and reliability.

In the call for environmental protection, energy conservation, pollution reduction, recycling and safe production, our country's packaging and printing water-based inks have ranked the top among other packaging printing inks with its 35% usage in just a few years.

The development speed of water-based ink makes other inks hard to beat. In the past, the poor gloss of ink on paper, poor water resistance, poor adhesion, difficult overprinting, discoloration and fading, and products that are easy to warp edges and corners have been improved. This is very beneficial to promote the application of water-based inks on cartons. In addition, the ink has the characteristics of non-explosion, no transportation hazard, no pollution, no toxicity, etc., and water is used to adjust the drilling degree and clean the printing equipment, which reduces the production cost and labor intensity, and reduces the hidden safety hazards for the production, transportation and users.

Keshenglong is professional carton packing machine exporter,our main products are flexo printing machine,flexo case-maker,die-cutting machine etc.

Different from manual packing, automatic packing equipment has higher requirements on carton creasing and grooving. What are they? Let's take a look.

1. The creasing line should be clear, creasing line and slotting position should be accurate.

2. Corner hole should not be too large.

3. The surface of the carton should be sealed with transparent adhesive.

4. The surface of  the finishing paper must have a certain roughness.

5. It has to have good flatness.

Anything about carton box printing machine’s question, welcome to contact us: kl@keshenglong.com.cn

Our Keshenglong Jumbo size Model K1 computerized flexo printing slotting die-cutting machine is unique and rare which makes it much more attractive than the other normal standard corrugated carton box flexo printing machines in the world.

Here’s one of our cases in Germany, customer bought our Model K1 Jumbo size carton flexo printing machine and runs normally. No matter the printing register precision, max. machine speed, slotting precision, die cutting precision, processed board thickness can reach each technical performance indicators on the technical contract.

The flexo printing slotting machine meets client’s production needs, which is what we want!

Below are some pictures of our client and the corrugated printing machine.

In the production process of corrugated cardboard, sometimes there will be some production problems, if it can not be solved in time, the whole production will be forced to stop.

Belows are some common problems occurs and solutions as your reference:

1. The corrugated is not high enough.

The reason may be the pressure or temperature is too low, or moisture content is too high. And the solution is to adjust the pressure or roll temperature, or reduce the speed to dry.

2. Corrugated height is not uniform, the length of the sheet on both sides that pressed out are different which likes circular sector.

This is due to the corrugated roller parallelism is not good or uneven pressure at both ends. If the left corrugated sheet is shorter than the right, it’s better to raise up the left side of the top corrugated roller,  otherwise to do the reverse adjustment.

3. Corrugated sheet curl like tube shape, the main reason is that the temperature difference between the upper and lower roller is too obvious.

You should check the heating source in the upper and lower rollers. It may be repaired or replaced if one of the heating sources break down.

4. The corrugated sheet is stuck to the surface of the corrugated roller.

The roll surface temperature is too high or the moisture content of raw sheet is too large will occur this situation. At this time, you should adjust the temperature of the roll surface to let the sheet be dry and then crease, if the doctor blade and roll groove is not fit, you should adjust or replace it.
