01 — Two ways to buy

Same factory, same standards, different starting point

You own the design, or you start from ours

The distinction matters before the first email: it decides what you send, who holds the tooling, and how fast a quote can be fixed. Both routes run through the same presses and the same inspection.

OEM Your geometry, our tooling

Built to your drawing

You send the 3D file or a sample. We return a DFM note in 48 hours: what will not mold, what tolerance the process can hold, where the gate should sit. Then a fixed tooling price and a unit price by quantity. The tool is yours once it is paid for.

Fastest when the drawing is completeStart with a 3D file

ODM Our molds, your brand

Private label from 300 pcs

Existing platforms across six domains: masking plugs, O-rings, liners, rollers, kitchen goods. Colour, logo, packaging and kit configuration change; the mold does not. +3 days when the specification is fixed up front.

Fastest when a part number existsStart with a part number

02 — What we make

Six domains · every sub-family has its own page

Six domains, each with its own manual

Not a catalogue of shapes — six process positions. Each domain carries its own parameters, its own boundaries and its own failure modes, written down. Pick the row that matches what you are holding.

03 — Measured, not claimed

Numbers we will put in writing

The four numbers a buyer checks first

Every one of these appears in the quotation, not only on this page. If a value cannot be held on your part, the DFM note says so before tooling starts — that conversation is cheaper before the mold, not after.

±0.05 mmOn LSR diameters, first article and per lot.

04 — How a quote happens

Three steps, three dates

From your file to a part you can approve

Most custom-silicone inquiries take three or four email rounds to become quotable. This is the shortest path we know: send the four things, get two documents back.

Step 01 · Send the input

A 3D file, a drawing, a sample or an OEM part number

One photo with a ruler beats five paragraphs of description. If the file is incomplete we say which dimension is missing.

Reply within 24 hours

Step 02 · The documents

Get the DFM note and a fixed quote

Two pages: what will not mold and why, gate and ejection, tolerance per feature. Then tooling price, unit price by quantity, and the date T1 samples leave the press.

In 48 hours, in writing

Step 03 · The run

Approve T1, then run

T1 samples with a dimension report. You approve the golden sample, we hold it against every subsequent lot. Existing-mold orders ship in 10 working days.

T1 in 30 days

05 — What we don’t do

Stated before you ask

The boundaries are part of the specification

A supplier who accepts everything is telling you they have not run enough projects to know where the process fails. These five are declined on purpose.

  • Silicone bonded to PP / PESurface energy 29–31 mN/m. Mechanical interlock only — change the substrate or the design.
  • Fuel and aromatic-oil serviceSilicone swells and loses strength. FKM is the correct material; we name it instead of quoting.
  • Regrind in food-contact compoundsTraceability ends at the regrind bag. No lot documentation, no order.
  • Glass-filled PC above 30%Bond strength collapses at the interface. Plasma plus primer, or a different substrate.
  • “100% in-house” claimsSome processes are partnered and labelled as such on the page. Nothing is presented as ours when it is not.
