Injection Mold for Electronic Parts

Production molds for electronic parts

Molds for electronic parts usually run large volumes, so they must last longer than most tools. Many of these parts are also visible, which means they need a high surface finish and very clean parting lines: a step or flash line on a phone or device cover is a reject.

Reliability and stability first

Our team gives extra attention to reliability and stability in both mold design and mold making:

• Hardened or pre-hardened steels chosen for the expected mold life.
• Interlocks and guiding that keep cavity and core aligned over millions of cycles, protecting the parting line.
• Cooling designed for short, stable cycles.
• Wear plates and replaceable inserts where sliding parts meet.

Precision machining for clean parting lines

A clean parting line starts with precise machining and fitting. We use high-speed CNC machines such as Makino and DECKEL MAHO, and Charmilles mirror EDM for fine cosmetic details, then fit the parting surfaces by hand where necessary. Surfaces are polished or textured to the agreed standard.

At T1 we inspect the parting line, gate marks and surfaces under controlled lighting, as well as dimensions, before the mold is approved.

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.
