Injection molding chiller
来源: | Author:AUWII | Time:2020-12-16 | 184 Access | 分享到:
The plastics industry is one of the largest and most important industries in the world, affecting nearly every aspect of our lives, from food and medicine to entertainment and aerospace. The majority of plastic parts used everyday are injection molded. Injection molding is an extremely effective way to mass produce identical components with very little waste material. An injection molding machine heats plastic particles until they become molten and then injects them into a shaped mold where the plastic part cools. The cooling process can be very lengthy; over 80% of the total plastic manufacturing time is devoted to cooling. An injection molding chiller will drastically reduce the cooling time and preserve the quality of your products.

The cooling process can be very lengthy; over 80% of the total plastic manufacturing time is devoted to cooling.

Temperature plays a critical role in the entire process of injection molding.  Plastic pellets must be heated to specific temperatures in order to melt and enter the mold.  Following the actual injection, cooling must begin immediately. The longer it takes for the product to cool in the mold, the more time and money is lost.  Cooling efficiency is a must for successful plastics operations.


The cooling process varies depending upon the size, thickness, and type of plastic used. Using a water cooled injection molding chiller to cool the mold cavity will not only help reduce the duration of the process, but can improve the quality of the plastic.  If cooled incompletely, the plastic in the mold can warp and deform when it is ejected from the mold, causing costly mistakes.

 

Benefits of Using a AUWII Injection Mold Chiller System:

1. Reduces Scrap Count: a consistent and reliable supply of the proper temperature to the process which means less scrap.

 

2. Better Heat Transfer Rates, Less Maintenance and Downtime: because a chiller uses a closed water loop, a better quality of water will be used, resulting in better heat transfer rates, less required maintenance and decreased downtime.

 

3. Colder Water: a chiller can produce much colder water (or water/glycol mixture) than any of the other cooling alternatives, giving you certain advantages under some circumstances.
