Rubber and Plastic Products
Custom Plastic Parts
Custom plastic parts made to your specification by injection moulding, extrusion and assembly.
Product Overview
Custom plastic parts made to your specification by injection moulding, extrusion and assembly. The service covers both intricate designs and large-scale components, with the part designed and produced to the dimensions and function you require rather than selected from a standard range. Any shape, size and design can be produced within the process limits.
Key benefits
Why Buyers Choose This Specification
Injection Moulding and Extrusion Together
Moulded parts and extruded profiles come from the same supplier, so an assembly combining both stays under one purchase order.
Any Shape Size and Design
The versatility of plastic processing is what makes geometry cheap, provided it is designed with draft, uniform wall and a sensible parting line.
Assembly Included
Parts are assembled as well as moulded, so what arrives is the sub-assembly rather than a box of components.
Made to Specification Not Catalogue
Each part is crafted to your exact specification, which is the entire point of custom moulding over off-the-shelf parts.
Application scenarios
Where It Is Used
- Injection moulded housings and enclosures
- Extruded profiles and sections
- Intricate small components in volume
- Large-scale moulded components
- Moulded sub-assemblies requiring assembly work
- Replacing metal parts with moulded plastic
Who it is for
The Buyers This Product Suits
Product Manufacturers
Custom moulding is how a product-specific part exists at all, once volume justifies the tooling.
Equipment Builders
Housings, covers and internal components in plastic reduce both weight and cost against fabricated metal.
Buyers Needing Assembly
Assembly is part of the service, so components arrive built rather than loose.
Problems it solves
What It Fixes
No Standard Part That Fits
Custom parts are designed to your exact specification rather than adapted from a catalogue.
Assemblies Sourced From Several Suppliers
Moulding, extrusion and assembly in one place removes the co-ordination between them.
High Piece Cost on Machined Plastic
Once volume justifies a tool, moulding costs a fraction of machining per part.

How It Ships And What Comes With It
Packing And Loading
Shipping volume for this item depends on the configuration and capacity you select, so no fixed container figure is published. Confirm the specification and the destination and a loading plan is issued with the quotation, rather than a figure we cannot support.

Sourcing And Inspection
This product is supplied through TrueGlow Imaging, working with manufacturing partners whose facilities are visited and verified rather than taken on trust. In-process quality control and delivery supervision are available so goods are inspected before the container is sealed. Certifications quoted on this page are those stated on the product specification and belong to that product range rather than to our trading entity, so ask for the certificate covering your specific item.
Handling guide
Getting It Right First Time
Step 1
Send a 3D model with the function described, not just the geometry.
Step 2
Design for moulding: uniform wall thickness, draft angles and a sensible parting line.
Step 3
Confirm the material grade, since it affects shrinkage and therefore the tool.
Step 4
Discuss tooling cost against expected annual volume before committing.
Step 5
Approve a first article from the production tool before the full run.
Comparison
How It Compares In Our Range
Two plastic processes for two part shapes.
| Injection Moulding | Complex three-dimensional parts in volume. Tooling cost up front, very low piece cost afterwards. |
|---|---|
| Extrusion | Continuous profiles of constant cross-section, cut to length. Much cheaper tooling, but only for constant sections. |
FAQ
Custom Plastic Parts Questions
What processes do you offer?
Injection moulding, extrusion and assembly.
Can you make any shape?
Parts can be made in a wide range of shapes, sizes and designs within the limits of the process. Send the model for confirmation.
Do you assemble the parts?
Yes, assembly is part of the service.
Do we pay for tooling?
Injection moulding requires a tool, which is quoted separately. Extrusion tooling is much cheaper.
What quantities do you handle?
From intricate small components to large-scale production volumes.
What do you need to quote?
A 3D model, the material, the annual volume and any assembly requirement.

Selecting an O-Ring Material NBR EPDM FKM or FFKM
Almost every seal failure is a material selection error rather than a dimensional one. The fluid and the temperature decide the elastomer, and the size is the easy part.
