Custom Plastic Parts
Custom plastic parts produced by injection moulding, extrusion and assembly, made to each customer's specification rather than selected from a catalogue. The process allows parts of almost any shape, size and design within the limits of the tooling, from intricate components through to large scale mouldings.
- Engineering and commodity thermoplastics per specification
Product Overview
Custom plastic parts produced by injection moulding, extrusion and assembly, made to each customer's specification rather than selected from a catalogue. The process allows parts of almost any shape, size and design within the limits of the tooling, from intricate components through to large scale mouldings.
Key Benefits
- Parts made to your specification rather than adapted from a standard item
- Injection moulding, extrusion and assembly available on the same order
- Intricate detail and large components both within scope
- Consistent quality across a production run once tooling is proven
- Materials selected for the application
Problems It Solves
- Catalogue parts that do not fit the design
- Prototype parts that cannot be reproduced consistently in volume
- Tooling cost quoted without a clear process route
- Separate suppliers for moulded parts, extrusions and assembly
Where It Is Used
Applications And Buyers
Application Scenarios
- Housings and enclosures for equipment
- Extruded profiles and trims
- Assembled plastic sub components
- Replacing metal parts with moulded plastic to save weight and cost
Who It Is For
- Equipment manufacturers specifying moulded components
- Product designers taking a design into production
- Companies consolidating plastic and rubber parts with one supplier
- Buyers replacing an obsolete plastic part

How It Is Made And Checked
Materials Process And Quality Control
Materials
- Engineering and commodity thermoplastics per specification
Manufacturing Process
- Injection moulding
- Extrusion
- Assembly
Quality Control
- Specification agreed in writing before production starts
- First article or sample approved against the agreed specification
- Goods inspected and photographed at the factory before loading
- Inspection report sent to you before the container sails
Customisation Options
What Can Be Varied
- Part geometry to your drawing or 3D model
- Material grade chosen for the application
- Colour and surface finish
- Insert moulding and assembly operations
- Tooling cavity count for the production volume
Compared With The Alternatives
| Machined plastic parts | Machining suits very low volumes and needs no tooling; moulding is far cheaper per part once the quantity justifies the mould. |
|---|---|
| Metal components | Moulded plastic saves weight and cost and needs no finishing, but the loads and temperatures have to be within what the material can take. |
Use Guide
- Send a 3D model so wall thickness and draft can be reviewed before tooling
- Specify the material grade and any regulatory requirement early
- Set cavity count from the annual quantity
- Approve a first article from the production tool before the run
