2K Injection Tooling

Two materials, one shot, no bonding operation afterwards

Polished multi-cavity mould inserts before assembly into the mould base

Sanpin Mould · since 2007

Overview

Multi-material injection tooling that combines two materials inside a single moulding cycle. The rigid structure and the soft or contrasting material come off the machine already joined, which removes the assembly step and the adhesive that usually fails first.

Problems

What This Fixes

  • Two-part assemblies where the bond line is the weakest point of the product
  • Labour cost and scrap generated by a separate over-moulding or gluing operation
  • Soft-touch surfaces that peel away from the substrate in the field
  • Colour or material transitions that have to be crisp and repeatable

Benefits

What You Get

  • Complex components produced from different materials in one process
  • One tool instead of a tool plus a bonding fixture
  • Material pairing reviewed at design stage against the resins we run
  • Tooling built and sampled in the same shop that will mould the production parts

Who For

Suited To

  • Product teams designing grips, seals and soft-touch surfaces
  • Buyers who want an assembly step removed from their cost sheet
  • Designers working with contrasting colours or hard-soft combinations

Scenarios

Typical Jobs

  • A handle with a rigid core and a soft over-moulded grip
  • A housing with an integrated gasket rather than a fitted one
  • A part with a moulded-in colour marking instead of a printed one

Technical

How It Runs

  • Multi-material injection capability for complex single-cycle components
  • Shot sequencing and rotation handled at tool design stage
  • Moldflow used to settle two-stage filling before the steel is cut
  • Sampling covers both materials and the interface between them

Order Process

How This Job Would Run

The same eight stages apply whether the order is a single tool or a production programme.

Request A Quote

Send the part drawing or 3D file by email. An engineer comes back within 24 hours with a consultation, not an auto-reply.

DFM Report

Before any steel is cut we return a design-for-manufacture report that flags flaws and errors in the design, so they are fixed on paper.

Mould Design & Moldflow

A predictive model analyses how the molten material behaves inside the cavity. Flow analysis settles gating and cooling before tooling.

Mould Tooling Production

Tooling is cut from the steel grade chosen for the application, not from whatever is on the rack.

T1 Sample Inspection

First-trial samples go out for your inspection and review. Errors are identified on T1, before mass production is committed.

Low Volume Production

A low-volume run follows the trial phase, so precision is proven on real machines under expert surveillance before the ramp.

Strict Inspection

Parts are inspected against international tolerance standards and against the specification you supplied.

Delivery

Parts are packaged to survive the journey and released through our logistics partners on a scheduled delivery.

Questions

About 2K Injection Tooling

What is the advantage over over-moulding in two operations?

The two materials are combined in one process, so there is no separate handling step and no adhesive interface to fail.

Can you advise on material pairing?

Yes. Pairing is reviewed during the DFM stage against the resins listed for our injection tooling, before the tool is designed.

Is 2K available at low volume?

2K tooling is quoted alongside our low-volume moulding service, so a limited run can be produced before a full production tool is committed.
