Equipment & Process

An honest look at how the workshop is set up — where each step happens, what we run in-house, and what runs through long-term partners under our own tooling control.

Mold Design

In-House Design in UG / CAD

Every mold begins with in-house design work in Siemens NX / UG (with 2D drawings in AutoCAD). Part designer and mold engineer sit in the same office, which is how DFM discussions happen inside a day, not a week.

DFM review before quote confirmation
Parting line, gate location and gate type (side / submarine / pin-point)
Ejection plan — pin, blade, sleeve, lifter
Cooling plan — line diameter, baffles, spiral cooling where needed
Slider and lifter design, angle and travel
Buyer sign-off on 3D mold layout before machining starts

CNC Machining

Supported by Long-Term Partners

CNC machining is supported by long-term machining partners under our process and quality control. These are shops we have worked with for years — not a random subcontractor for each job.

CAM programming reviewed by our tooling engineers
Tool paths agreed for critical surfaces before cutting
Every returned part inspected against the drawing before fitting
Traceable material and heat treatment records

Why we say this: the honest label matters more than a marketing claim. You get the same result as an in-house CNC step — the same tooling engineer runs it — but we are not going to pretend a shop is bigger than it is.

EDM, Fitting & Assembly

In-House Where Skill Matters Most

The steps that most affect mold life and part quality are all in-house. This is where 25 years of workshop experience actually shows.

Sinker EDM — ribs, sharp corners, logos, text
Wire EDM — ejector holes, precision slots, inserts
Fitting — parting line, shut-offs, slider faces by hand
Assembly — mold base + core + cavity + slider + lifter + ejector + cooling
Polishing — from SPI-A3 to optical polish for PC / PMMA lenses
Correction after T1 — welding, re-cutting, insert changes as needed

Trial Molding

90T – 200T Machines, In-House

Every mold is tried in-house before it ships. Our injection molding line covers 90-ton to 200-ton machines, matched to the mold size we build. Robots handle unloading on the machines where they are useful.

Inspection

Documented, Not Assumed

Inspection happens at three points: on machined parts before fitting, on the assembled mold before T1, and on trial parts before shipment. The paperwork ships with the tool.

CMM inspection of critical part dimensions
Cavity and core dimensional check against 3D reference
Appearance check on trial parts (weld lines, sink, flow marks)
Assembly check — every action cycled by hand and under power
Final inspection before packing
