Injection Molding for Switch Plastic Parts

Molding switch plastic parts

Switch housings have many small pockets, thin walls and precise locating features for contacts and springs. This housing is molded in 30% glass-filled PA66 for stiffness, heat resistance and electrical insulation.

As a one-stop supplier we provide engineering, mold making and molding in-house, all under one quality system that covers engineering, tool making and molding.

Precision starts in the tool shop

The accuracy of a switch housing depends on the accuracy of the mold components. Small cores and inserts that form the pockets are machined on high-speed CNC and EDM, then checked on CMM. If an insert is out of tolerance, every part from that cavity will be too.

• Two cavities in AISI H13, cold runner, HASCO standard.
• Thin cores supported and cooled to resist deflection under injection pressure.
• Shut-offs fitted precisely so no flash enters contact pockets.

Molding capacity

We run 14 injection presses from 80 to 400 tonnes, so small switch parts are molded on small presses for an economical part price, while larger housings move to bigger machines without leaving our plant.

How a project like this works

• Tell us what you need – the mold only, molded parts, or both, and your estimated annual volume.
• Send drawings – STEP, IGES, STL, DWG or PDF, or a sample. We sign off moldability in a DFM review.
• Quotation – tooling price, part price and a schedule, with steel, cavities and runner proposed.
• Mold design approval – you approve the 3D mold design before steel is cut.
• T1 samples + FAI report – production or mold shipment starts after your approval.

Shipping molds and parts

• Molds are cleaned, rust-protected, marked and checked against a shipment checklist: cooling circuits, sprue, locating ring, ejection and support pillars.
• Molds ship with drawings, a spare-parts list and the T1 process sheet.
• Parts are packed to your packing instruction and inspected before shipment.
• We ship to customers in Europe, the USA and Asia.
