Custom parts: quality and specification

Quality, specification and supply

The numbers a buyer asks for, on one page, for custom parts made to your drawing. Because we compound, tool and cure under one roof, a fault is caught where it starts: in the mix, not on your assembly line. Figures are typical and are confirmed against your part at quotation.

Typical figures, confirmed at quotation.

Lead time

Confirmed per enquiry.

Ask for dates with your quotation. Every custom part moves through the same four stages.

STAGE 01

Quotation

On receipt of your drawing or sample.

STAGE 02

Tooling

Cut in-house after approval.

STAGE 03

Sample

First-off for your sign-off.

STAGE 04

Production

To your delivery schedule.

Repeat supply

No re-development on a repeat order

Tooling stays with us and the compound is on record, so a repeat order runs to the same recipe, the same hardness and the same section.

Quality

Checked in-house, at every stage.

Inspection

Three checkpoints.

Checked before mixing

Polymer, filler and curative checked against specification and batch record before mixing.

Checked before the run

Every batch mixed to a recorded recipe. Hardness and cure confirmed on a test piece before the run.

Checked before packing

Dimensional and visual inspection to the approved first-off sample before packing.

Working to your specification

Send the standard with the enquiry

If your part carries a standard, a compliance requirement or an inspection plan, send it with the enquiry. We will confirm in writing what we can meet before you raise the order.

This page covers custom parts made to drawing. For ready items ordered by size, code or machine, see the standard range.
