Injection tooling for electronics

Enclosures, covers and handheld housings, where the tooling problems are sealing faces, snap latches and apertures that must not flash.

Electronics housings are the largest group in the TJ-Teck reference parts. An enclosure with a moulded sealing lip, a fascia cover with a printed mark, a keypad cover full of apertures and a handheld handle all appear in the current range.

The engineering work concentrates on three features that decide whether an electronics housing is accepted: the continuity of the sealing face, the survivability of aperture shut-offs, and the consistency of a printed or textured surface.

What matters here

Four things this sector gets wrong most often

1

Sealing faces on a single piece of steel

Where the geometry allows, the gasket contact face is kept off any parting line or insert joint, because a witness line across a seal is the standard cause of an ingress complaint.

2

Shut-offs built to last a production run

Every aperture is formed by steel touching off between the two halves. Touch-off angles and the steel behind them are reviewed as a named DFM item.

3

Decoration treated as part of the tool

Pad printing fixtures are machined from the same CAD data as the cavity, so the print position does not drift as sample parts wear.

4

Component brands your service team already stocks

Mould bases and components from Hasco, DME, Meusburger, Misumi and the rest, so a tool that ends up in your own plant is maintainable there.

Reference parts

TJ-Teck parts used in this sector

Moulded black electronic enclosure box with integrated snap latches and cable port

Electronic Box

A moulded enclosure with integrated snap latches, a cable port and a sealing lip, built so the housing closes and seals without added hardware.

View part Long black injection moulded plastic cover with a white pad printed icon

Plastic Cover with Pad Printing

A long, slim appliance fascia cover moulded in one shot and decorated with a pad printed mark, so the panel leaves the tool shop already branded.

View part Pair of black moulded covers with button apertures and textured surface

Plastic Cover

A moulded cover with button apertures and a textured face, the kind of part where aperture position and texture consistency decide whether it is accepted.

View part White moulded electric toothbrush handle with moulded button apertures

Toothbrush Handle

A slim handheld handle with moulded button apertures and an indicator window, the classic case for a two-shot over-mould once a soft grip is added.

View part Blender jar assembly combining a clear moulded bowl, blade holder and blue-green lid

Blender Assembly

A multi-part appliance assembly: a transparent bowl, a coloured lid and a blade carrier, each with its own tool and all of them having to fit each other.

View part Transparent moulded cup with fine external ribs, produced in a polished clear tool

Thread Clear Part

A transparent moulded cup with fine external ribbing and a threaded feature, run in a mirror-polished cavity where every tool mark ends up visible in the wall.
