Over moulding- One plastic moulding over other plastic
Over moulding is the precision plastic injection moulding process, which moulding one material over a other material. The first moulding plastic is hard, and the second is soft. It is two layers!
For moulding material, proper material selection is critical – the two plastics must be not the same, they should be different hardness and melting.
For example: you should not plan on injection moulding the second material onto the first material if the second material will melt or distort the first material. One should not deform the other where it matters.
If the proper materials have been chosen, the two materials bond together chemically and mechanically. This process yields a strong finished piece with a long life.
Over moulding Resin
Our staff works with a wide range of engineered resins and can help you select the best resins and moulding process to deliver consistent, reliable product quality. It isAcetal, Delrin, Glass Filled Nylon, HDPE, PVC, TPU or TPE etc.
Over Moulded Samples
Our engineers do everything from over moulding electronics. We have years of experience helping customers optimize the best solution for their specific product.
Difference between Over moulding & Insert moulding
Insert moulding is putting insert when it is moulding, the insert is a metal object or ceramic any hard part, which is must be able to withstand the high-temperature and pressure of the injection moulding process.such as a pin, blade, threaded rod, electrical contact, wire, etc.
In a word, Insert Moulding is two different material, metal and plastic, metal is inside and plastic is around. Over Moulding is two layers. The outside plastic is soft, such as TPE or TPU.
