Low Pressure Overmoulding

Low pressure overmoulding uses a range of materials specifically designed to flow under lower pressures than typical injection moulding methods, this process is ideall for the encapsulation of PCB's or other delicate components.

Low pressure moulding also generally offers a lower tooling cost than standard injection moulding. This lower initial investment makes this process much more suited to low and medium volume applications where a professional moulded finish was previously not a viable option.

Greenstock works with a range of different materials for the low pressure moulding process to provide a service that is suitable for many different applications. materials bond well to a number of different substrates meaning high IP protection levels are possible, sealing and anchoring cables and bonding with clean steel, solders and other metals. a range of materials in black, clear and opaque finishes are available as well as a range of shore hardnesses. there are also specific materials which are designed for high temperature, oil or other fluid resistance and materials specifically for under hood applications.


Low pressure moulding techniques are also particularly suitable for the overmoulding of delicate components such as micro connectors, PCBA's and soft connector seals. this is often done as a first stage moulding to encapsulate parts and even up wall thicknesses. with an outer skin then applied through using high pressure moulding techniques.
