Injection tooling for industrial & agriculture equipment
Closures, covers and housings for equipment that lives outdoors, where a thread that leaks is a warranty claim.
Industrial and Agriculture Equipment is the third plastic parts group defined on the TJ-Teck site. The parts are less about cosmetics and more about sealing, wall strength and parts that survive being taken apart in a field rather than on a bench.
That makes unscrewing moulds and enclosure tooling the centre of the work: threaded caps with no parting line through the flank, and housings with continuous sealing lips.
What matters here
Four things this sector gets wrong most often
Threads off an unscrewing core
A split-core thread leaves two flash lines down the flank and those lines are the leak path. TJ-Teck builds unscrewing moulds as a standard mould type.
Enclosures with an uninterrupted gasket face
The sealing lip stays on one piece of steel wherever the geometry allows, so nothing crosses the gasket contact.
Steel grades chosen for the run, not the sample
The quoted grade is stated on the quotation, from 1.1730 and 1.2311 through 1.2738 and its H and HH variants to 1.2343, 1.2344 and H13.
Wear items designed as replaceable inserts
Shut-offs and cores that take the wear are designed as inserts, so field-service volumes do not turn into a weld repair on the whole block.
Reference parts
TJ-Teck parts used in this sector
Cap with Threads
Plastic moulded part with a thread structure: an internally threaded cap with a moulded spout, released by an unscrewing mould rather than a split core.
View part
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
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.

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.
