Production lines, cooling systems can help control the temperature of an extruder to avoid overheating that compromises plastic product quality and uniformity. 1HP chillers provide continuous and stable cooling for small extruders, thereby improving product uniformity and lowering scrap rates.
One of our customers, a small plastic injection molding factory that specializes in producing plastic parts, contacted us. The factory, specializing in automobile and electronic accessories, has seen an increase in production orders, which has necessitated long run times at high temperatures to fulfill orders quickly. Unfortunately, this has resulted in fluctuations in product quality and excessive wear and tear on the equipment. In order to address this problem, the factory decided to purchase a 1 HP chiller as an antidote.
Cooling in a barrel
When melting and plasticizing plastics, the head of an extruder makes a lot of heat. Plastics may not flow as smoothly or as well if the temperature is too high. A 1 HP chiller sends cold water through its cold water pipe to the cooling jacket outside the barrel to keep temperatures in the right range, which is usually between 20 and 30 degrees. You can keep the shaping effects smooth by keeping the temperatures stable and reducing temperature changes.
Don't cool down
When the extruder is working, the screws make contact heat. To get rid of this extra heat, a 1HP chiller can use its cooling water pipe to send cool water straight to the extruder's internal pipe. This direct touch with the cooling water keeps the temperature within safe limits, which stops the plastic melt from getting worse or less even because it got too hot.
Mold drying out.
After the barrel and screw processing is done, the plastic melt will be poured into a mold. Mold cooling is very important for keeping the shape and quality of the surface of the product. A 1 HP chiller sends cold water quickly through the mold cooling channel of a cooling tower. This keeps the mold temperature within its range (usually 10–20) for molding, which keeps finished goods from deforming, warping, or having surface flaws.
An extra cooling system
Some extruders use an extra cooling device that uses cold air to lower the temperature more accurately and evenly, in addition to direct cooling. A 1 HP chiller can provide cold water for air cooling systems when both systems are used together. This makes it easier to control the temperature of each part more accurately and evenly.
Precise temperature control
1HP chillers typically include accurate temperature controls to maintain an ideal cooling water temperature within a set range. This feature is especially important for smaller extruders, as fluctuations in temperature can dramatically change the viscosity of plastic material, thus altering product quality and consistency.
Small and easy to install.
Compact 1HP chillers are easy to install near production lines with limited space due to their small footprint, which allows them to take up minimal floor space while still offering flexibility in layout design. Installing these chillers near extruder production lines, which don't offer enough floor area for more conventional chillers, helps save both space and money.
Energy savings and efficiency
Compared with high-power chillers, 1 HP chillers feature lower energy consumption while meeting the cooling needs of small extruders. As part of an SME's overall economic benefits strategy, these chillers not only meet cooling requirements while also cutting operating costs and producing positive economic returns.
