Plastic Mould Injection & Design

Precision moulds.
Repeatable quality.

KT PH takes plastic components from CAD drawing to mass production — designing, machining and moulding high-tolerance parts that hold their spec cycle after cycle.

Who We Are

One roof. Design, steel & production.

Most mould problems start with a design that was never checked against the press it would be run on. At KT PH, our designers and toolmakers sit in the same building — so DFM feedback happens before steel is cut, not after the first trial fails.

We build moulds to be maintained, not replaced: documented builds, standardised components and preventive service plans that keep your tooling producing parts within spec for years.

  • 01

    In-house tooling

    CAD design, CNC machining, EDM and wire-cut under one roof — fewer handoffs, faster corrections.

  • 02

    DFM-first engineering

    We review part geometry for flow, warpage and ejection before quoting — saving cost where it matters most.

  • 03

    Transparent milestones

    Design approval, T1 trial report, PPAP-style documentation and clear communication at every stage.

Capabilities

What we do, end to end

Mould & Tool Design

CAD-driven mould design with DFM feedback — gate placement, cooling and ejection optimised before steel is cut.

Injection Moulding

In-house moulding across commodity and engineering resins, from short runs to high-volume production.

Rapid Prototyping & Soft Tooling

Urethane casting and aluminium soft tooling to validate fit, function and finish ahead of hard steel.

Machining & Tool Making

CNC milling, EDM and wire-cut for precision core & cavity work in hardened tool steels.

Surface Finishing & Texturing

Mirror polish to VDI textures — surfaces that look as good as they perform, plating-ready on request.

Quality Inspection & Metrology

CMM dimensional verification, first-article reports and in-process checks at every production stage.

Process

From drawing to delivery

A disciplined five-step path that keeps scope, schedule and tolerance under control.

  1. Consultation & DFM Review

    We review your drawings and specifications, flag manufacturability risks early and recommend improvements that reduce cost without changing the part.

  2. Mould Design & Approval

    Full 3D mould model with flow analysis, cooling layout and a detailed quotation — signed off by you before machining starts.

  3. Tooling Fabrication

    In-house machining of core, cavity and ejection in hardened steel, with dimensional checks at each major step.

  4. Trial Runs (T0 / T1)

    Trial shots evaluated against spec — dimensions, cosmetics and assembly fit. Every adjustment is logged until the part is right.

  5. Mass Production & QC

    Scheduled production runs with ongoing dimensional checks, material traceability and full reporting on request.

Industries

Built for demanding sectors

Automotive

Housings, brackets and connectors with PPAP-style documentation.

Consumer Electronics

Fine-feature enclosures and cosmetic surfaces for devices.

Medical Devices

Clean, controlled builds for housings and instrument parts.

Home Appliances

Large, textured components with consistent cosmetic finish.

Packaging

High-cavity tools for fast, repeatable production runs.

Industrial Components

Tough engineered resins for parts that take a beating.

Quality

Measured, not promised.

Every stage of our process is backed by documented checks — from incoming material to the finished part on the press. When a number matters, we can show it.

  • CMM dimensional verification at T-trial and in production
  • First-article inspection reports with every new tool
  • In-process SPC sampling on volume programmes
  • Material certification & batch traceability on request
  • Maintenance logs for every mould we build or service
