A Hardened Production Mould is a production process in steel: cooling, gating, venting and ejection have to work together before the first acceptable part appears. Designed for consumer electronics, this Hardened Production Mould is produced in aluminium for short runs and fast cycling with mould design, steel cutting, EDM detail, fitting and tool tryout. The figures below are the ones recorded at tryout rather than theoretical values.
Tolerance is applied where it does work rather than across the whole drawing. Critical features are held to cavity tolerance ±0.02 mm, non-critical dimensions follow the general machining tolerance, and the difference is stated in the quotation rather than discovered later.

Manufacturing process
Work is carried out with mould design, steel cutting, EDM detail, fitting and tool tryout. Tooling, speeds and fixturing are recorded with the part number, so a repeat order starts from a proven process instead of a fresh setup.
Material is purchased against a certificate and checked on receipt, so the composition is known before any cutting starts. Work in progress is identified by part number and operation, and the finished parts are deburred, cleaned and protected before they leave the machine area.
Typical applications
Most of the work supplied in this category falls into the following examples.
- Electronic housings and connectors.
- Automotive interior components.
- Medical device disposables.
- Appliance control panels.
- Packaging closures.
Quality control and documentation
Critical features are measured on calibrated equipment in a controlled room, and the results are filed with the job so that a repeat order can be compared with the first.
Material certificates to EN 10204 3.1, dimensional reports and first article inspection reports are issued with the shipment where the application requires them. Calibration dates and measurement uncertainty are recorded alongside every result.
Ordering, lead time and packaging
Packaging is specified by the part: individual protection for finished surfaces, separation for assemblies, and export crating with a packing list for shipment.
Frequently asked questions
How long does a mould take to build?
Prototype aluminium tools run 2 to 3 weeks, hardened production tools 6 to 10 weeks depending on cavity count, slides and the amount of EDM detail required.
What determines the steel choice?
Annual volume and resin. Abrasive or corrosive materials and volumes above a few hundred thousand shots justify hardened steel, while short runs are cheaper in aluminium.
How long does delivery take?
Sample parts are typically shipped in 7 to 15 working days after drawing approval. Production batches run 3 to 4 weeks depending on quantity, finishing and inspection requirements.
Drawings are reviewed for manufacturability before quotation, and any feature that adds cost without adding function is pointed out at that stage rather than after the parts are made.
