Typical parts

  • Interior clips, bezels and housings
  • Appliance panels and control knobs
  • Connectors and housings
  • Syringe barrels, caps, micro-fluidic parts
  • Closures and thin-wall containers

How we approach it

  • Flow balance is signed off on the 3D before steel is cut, with gate position locked only after a fill/pack/warp report.
  • Cavity and core are machined as matched pairs on one setup so parting lines stay closed after 500,000 cycles.
  • Wear plates and inserts are hardened and ground separately, so a production change is an insert swap, not a new tool.

  • Bracket and lead-frame parts

How we approach it

  • The strip layout is reviewed for carryover, tonnage and pilot-pin engagement before the die book is released.
  • Every pierce and form station is shim-adjustable, so press wear is compensated by grinding a plate, not scrapping the die.
  • Burrs and springback are measured per station at T1, and the corrective station is identified before any steel is removed.

Typical parts

  • Battery-tray frames and cross members
  • Motor and reducer housings
  • Bracket and seat structural parts
  • Housing for e-mobility inverters
  • Compressor and pump bodies

How we approach it

  • Solidification and filling are simulated with the actual machine curve, so the overfill and biscuit size are designed in rather than found at trial.
  • Thermal fatigue is the failure mode, so hot-zone inserts are made replaceable and the cooling circuit layout is documented for the owner.
  • Die-sinking is done in-house so electrode wear and corner radii are corrected the same day.

  • Fuel tanks and ducting
  • Medical reservoirs

How we approach it

  • Wall distribution is designed with parison programming curves supplied as part of the tool package, so the moulder starts from a documented setting.
  • Neck gauging is treated as the critical feature; thread and sealing faces are checked against a master every 20 cavities.

How we approach it

  • Shrinkage is set per compound and per direction, with the value recorded on the drawing so a re-order matches the first order.
  • Flash land geometry is standardised so trim tooling and the compression tool never disagree.

How we approach it

  • The gauge and the mould are modelled in one file, so a datum dispute cannot be settled twice with two different answers.
  • Wear points are replaceable and spares are listed on the delivery document.

Development process

Eight gates from drawing to handover. Each one leaves you a document you keep.

  • Requirement review

    Drawing, material, annual volume and your machine list are read together; the first quote therefore includes gate position and parting line, not just a price.

    Deliverable DFM report, 3 pages

  • Flow simulation

    Fill, pack, warp and cooling are run on the proposed cavity count, and the two or three options worth arguing about are put in front of you.

    Deliverable Moldflow / MAGMASOFT report

  • Tool design release

    2D tooling drawing plus 3D, with the change list closed before the die book is released for machining.

    Deliverable Approved die book

  • Machining

    Milling, boring, EDM and wire run from the same model; critical dimensions are measured between operations, not only at the end.

    Deliverable In-process CMM records

  • Fit-up and benching

    Hand-fit of parting faces, action and ejection, checked on the bench before the tool ever sees a press.

    Deliverable Bench-approval photos

  • T1 trial

    Trial on the stated machine class with the agreed material, and every dimension on the drawing measured on the resulting parts.

    Deliverable T1 parts + full dimensional report

  • Modify and validate

    Changes are made against the report, and T2 confirms the corrected features before sign-off.

    Deliverable Change log + T2 report

  • Handover or production

    The tool can ship with its documentation pack, or stay and run your parts with a recorded maintenance history.

Frequently asked questions

What do you need to quote a tool?

A 3D model (STEP) or a 2D drawing with tolerances, the plastic or strip material, expected annual volume and, if you have one, your press or machine specification. With those four we can quote a cavity count, a tool price and a T1 date.

How long until we see DFM feedback?

Three to five working days for a normal tool, and it arrives as a marked-up document with the questions we need answered — not a silent quote.

How many trials are included?

T1 plus one corrective round is included in the tool price. A second is rare and always quoted before any steel is removed.

Who owns the tool, and can we move it?

You do, once paid. Tools are etched with your part number, stored under an NDA, and shipped with the design records, spare-part list and maintenance log so a transfer is a document handover, not a rebuild.

Do you also run production?

Yes. Many customers keep the tool here for moulding; the same tool then carries a shot count and maintenance record, which is what makes a later transfer, or a re-order, predictable.

What happens at end of tool life?

We quote a refurbishment scope first — inserts, gates, slides and polished faces are normally replaceable — and only recommend a new tool when the base has moved.
