Two lines, one engineering discipline

We stay in our niche: not an injection mould shop, not a general job-work tool room.

Main line

Compression moulds

For SMC, DMC, Bakelite, melamine and urea-formaldehyde parts: enclosures, meter boxes, switchgear and wiring-device housings.

See compression moulds

SMC moulds

Enclosure bases, lids, meter boxes and large covers in sheet moulding compound.

See SMC moulds

DMC, Bakelite & melamine moulds

Switchgear parts, terminal blocks, wiring devices and BMC reflectors.

See DMC moulds

Second line

Die casting moulds

Aluminium junction boxes, flameproof enclosure parts, LED housings and motor terminal boxes.

Built for enclosure and housing makers

These parts need flame retardance, electrical insulation, weather resistance and zero corrosion. That is exactly what thermosets and compression moulding deliver.

Draft analysis map of an SMC enclosure base from a Prime Tools DFM report
3.7% of one enclosure base's surface was under 0.5° draft. Found and fixed in DFM, before tooling.

Problems are fixed on screen, not at the trial

Flash, cracks, blisters and non-fill are mostly designed in before the first trial. Every part gets a DFM and feasibility report that checks:

  • Draft on every wall, rib and boss
  • Wall thickness and material flow
  • Venting and ejection
  • Parting line and shear edges

How your mould is built

Core and cavity are cut in-house from the approved design, then fitted and trialled by the same team.

  1. Mould cavity being machined under coolant

    VMC machining

    Roughing and finishing on our BFW VMC, programmed from the approved mould design.

  2. Vision Electro EDM machine in the Prime Tools tool room

    EDM & wire cut

    Fine ribs, slots and sharp internal details.

  3. HMT surface grinder used for mould plates

    Grinding

    Plates and inserts ground flat and square on our HMT surface grinder.

  4. Ejector side of a mould with support pillars

    Fitting & blue matching

    Engraving, fitting and blue matching by hand, by people who care how the mould closes.

  5. Assembled compression mould with its nameplate

    Assembly

    The mould is assembled, nameplated and readied for trial.

  6. Multi-cavity compression mould on the press with the charge being loaded at trial

    Trial & delivery

    First-off parts approved before handover, then the mould is wrapped, loaded and sent to your press.

Project: SMC enclosure base and lid

  1. DFM review. Draft and wall-thickness analysis on both parts before tooling.
  2. Two compression moulds. Core and cavity for the base and its matching lid, built in-house.
  3. Trialled at 400 t. The base mould was trialled on a 400 t press.

Every mould is trialled before it ships

Real trials from our moulds: charge loaded, pressed, cured and released. You get the trial video and first-off parts before dispatch.
