Unscrewing Plastic Injection


Richfields Corporation uses decades of experience in manufacturing unscrewing plastic injection molds. The output is molds that are used for the production of internal threaded plastic injection parts. External threaded plastic injection do no need to be produced using unscrewing injection molds.

Detailed threads on the plastic parts cannot be easily removed from the mold using traditional knock-off, so unscrewing plastic molds have gained popularity not only for its quality but also as a means for cost savings. Unscrewing plastic injection molds can be more complex in design than most plastic injection molds

The molds are operated at high speed to realize faster cycle times. To prevent damaging the threads on the plastic part during production, unscrewing plastic injection molds are being used by the industry.

Unscrewing is widely used for plastic parts that require high volume of output during production. It also prevents damaging the threads on the plastic parts during production. We make unscrewing plastic injection molds to produce high quality parts such as:

Automobile Industry parts

Bolts and Nuts

Bottle caps and closures

Cosmetics containers

Consumer products packaging


Medical supplie
