CNC Engineered Plastic Parts Replace Injection Moulded

Partwell Group are receiving a large number of enquiries from clients that require a previously injection moulded part to be CNC engineered for a number of reasons.

One of the images is of a client’s used injection moulded nylon plastic part described as a balloon ring, operated on an industrial sewing machine to contain the threads. Injection moulding is a manufacturing process that is used for large volume production, once a tool or mould has been produced the design of the finished component is generally fixed, the moulds are usually very expensive but the price per component is low.

This client was looking for a small number of replacement parts, but their current injection moulding supplier would require a minimum order quantity of thousands, with an eight week production lead time and four week import transit time.  From the Lancashire based factory, Partwell Group CNC engineered a small number of direct replacement parts (see image) from the same grade of Nylon material.  The lead time was minimal as the plastic sheet material was in stock and the Partwell engineers hand delivered the parts to a local Lancashire firm.

Nylon is the perfect choice of material for this application as it is a strong, heavy duty material that also offers low co-efficient of friction – will resist wear as a moving component. Nylon is very easily CNC routered to bespoke parts.

Partwell Group provide a comprehensive Plastic Engineering service, everything from design assistance, 3D software, prototyping, 3 and 5 axis CNC machining of small and large volume orders, water jet cutting service and industrial plastic sheet and plastic rod stock holding.
