One-stop mould & moulding service

From mould drawing
to packed parts —
under one roof

A complete custom injection mould service: mould design, CNC machining, EDM and slow-wire EDM, mould assembly, trial and then plastic injection moulding of production parts with assembly on top. Nothing leaves the building.

What we do

Six services that make one supplier

Our one-stop service covers moulds from the mould drawing and mould design, through CNC machining, EDM and WEDM processing, to a high-precision export mould — and the parts that come out of it.

01

Mould design & DFM

Part review, draft analysis, gate and runner layout, cooling circuit design, ejection and slider strategy, steel and hardness selection — delivered as a mould drawing you approve before we cut anything.

02

CNC mould machining

Mould bases, cavities, cores and inserts machined on imported CNC centres to ±0.01 mm, with accuracy capability down to 0.001 mm on the Yasoda and OKUMA machines.

03

EDM & slow-wire EDM

Makino spark erosion and Swiss GF slow-wire EDM to 0.001 mm for sharp internal corners, deep ribs, narrow slots and hardened inserts that milling cannot reach.

04

Inspection & mould trial

Critical dimensions verified on Zeiss Contura and Hexagon CMM at ±0.002–0.005 mm, then a T1 trial on our own presses with samples and a trial report sent to you for approval.

05

Plastic injection moulding

30+ injection machines from 20 to 300 tons, plus a dedicated anti-dust moulding workshop for appearance-critical parts. Run your mould with us or ours.

06

Assembly & finishing

Assembly workshops for sub-assembly and finished goods, so you can receive a completed product instead of loose mouldings that still need a supplier to put together.

Step 1 — Engineering

The mould is designed before it is cut

Tooling problems are almost never caused by a machinist. They are caused by a decision made during design — a gate in the wrong place, cooling that cannot reach a hot core, ejection that marks a visible surface. That is why our founder's background is mould design.

Send a 3D file, a 2D drawing or a physical sample. Our engineers — 10 of them — review the part for manufacturability and return a design intent with the mould structure, cavity layout, gating, cooling, ejection and the steel specification. You approve the mould drawing, then steel is ordered.

  • Part and mould design review with written feedback
  • Gate, runner and cooling layout agreed before machining
  • Steel grade and hardness matched to your annual volume and mould life target
  • Mould drawing issued for your approval
Speciality

We are known for the moulds
other suppliers hesitate over

Two families of complex tooling come up again and again with our customers — and they are where our engineering earns its keep.

A Multi-material and overmoulded injection moulded components in clear, white, red and green plastic Overmoulding · multi-material moulds

Overmoulding & multi-material moulds

Some products need several different plastics bonded into one part — a soft grip over a rigid body, a clear window in an opaque housing, two colours that must not bleed into each other. In the trade these are overmoulded or "multi-shot" tools, and they are unforgiving: the second material has to bond chemically or mechanically, the shut-off has to seal against enormous injection pressure, and the part must still release cleanly.

We build these moulds in-house, which means the shut-off geometry can be adjusted on our own machines during trial rather than negotiated with a third party. If your part is a multi-material design, describe it in your enquiry — it is exactly the kind of work we want.

B CNC machining centre producing precision components for an unscrewing injection mould for threaded plastic parts Unscrewing moulds · rotating threads

Unscrewing moulds for rotating threads

When a moulded part carries an internal or external thread that cannot be stripped straight off the core, the mould has to rotate the core or the cavity and unscrew itself during ejection. That means a gear train, a reliable drive, correctly phased movement and a control sequence that cannot damage the thread if a cycle is interrupted.

We have been building these tools for closures, caps, tubes and technical threaded components. The thread form, pitch and start count on your drawing are translated into a working unscrewing action — and function-tested before the mould ships.

Step 2 — Production

Plastic injection moulding, on your mould or ours

Not every customer wants to run tooling themselves. We have 30+ injection machines from 20 to 300 tons specifically to produce moulded parts for customers who need our factory to make the components, not only the mould.

Small precision parts run on the low-tonnage presses; larger housings and packaging components run on the bigger machines. For parts where a dust mark, a flow line or a weld-line bloom would fail your inspection, we move production into our anti-dust moulding workshop, which is separated from the general moulding floor.

  • 30+ presses, 20–300 tons, covering small precision parts to larger housings
  • Dedicated anti-dust moulding workshop for appearance-critical mouldings
  • Common materials: ABS, PP, PC, PA6/PA66, POM, PMMA, TPU/TPE, PC+ABS, PS, PBT, PET
  • Parts inspected and a QC report issued — 100% QC report for every part
Deliverables

What lands in your inbox

A mould project is a paper trail as much as a steel block. This is what you get at each stage.

Quotation

Mould price, part price at your annual volume, and a realistic lead time — prepared from your file, not from a price list.

Mould design & DFM

Mould drawing for approval plus written manufacturability feedback on your part design.

Progress photos

Machining, EDM and assembly stages photographed so you can follow the tool without asking.

T1 samples & QC report

Sample parts for approval, a trial report, and CMM dimensional data for the critical features.

Material, annual volume, tolerance and the surface that has to look perfect — that is enough for us to tell you whether the tool is straightforward or needs real engineering.
