Quality & metrology
Precision is a measurement, so we publish the measurement. Mold work is held to ±0.01 mm; our inspection centre resolves to 0.001 mm and every part we ship can be accompanied by its own dimensional report.
CENTS inspects molds and molded parts in-house on a Swiss Hexagon 860 CMM (0.001 mm accuracy) and a Zeiss Contura machine. Mold work is held to ±0.01 mm, and the inspection centre works in the ±0.002 to ±0.005 mm band on critical features. Every shipment can be delivered with a dimensional report, material certificates, mold drawings and a running-parameter sheet, so your engineering team receives evidence rather than a promise.
Inspection centre
Mold accuracy lives or dies at the measurement stage. A tool that was “close enough” on the bench becomes a trial-run problem, then a customer problem. So measuring is a separate, climate-controlled step in our process — not a caliper check at the machine.
Process control
Mold steel, standard components, hot runner systems and resins are checked against their certificates and order specification before they enter the build. Steel grade substitutions are never silent — they are confirmed with you or rejected.
Critical cavity, core and shut-off dimensions are verified during machining and after wire-cut and EDM steps, so errors are caught at the machine instead of at assembly.
Parting line, shut-offs, slide and ejector fits, water-circuit leak test and hot runner wiring are validated on the assembled tool before it is mounted on a press.
The mold runs on our own press. Sample parts are measured against your drawing and you receive the report with photos and video of the tool running.
Steel corrections, gating or cooling changes and texture/polish tuning are logged and re-sampled until the part matches the drawing and the cosmetic requirement.
Before shipment the tool is inspected, protected, packed with its spare-part set and handed over with the full documentation package.
Documentation
Offshore tooling becomes painful when the paperwork does not travel with the steel. Our standard handover package is designed so your team can maintain, re-run and audit the tool without calling us first.
| Document | Contents | Format |
|---|---|---|
| Mold drawings | Assembly, cavity, core, plate and mechanism drawings as approved | 2D PDF/DWG + 3D STEP |
| Dimensional report | Measured values on drawing-critical and customer-designated dimensions | PDF / Excel |
| Steel & component certificates | Cavity/core steel grade, hot runner and standard component data | |
| Molding parameter sheet | Barrel profile, mold temperature, hold pressure, cycle — the settings the tool ran on | PDF / Excel |
| Spare-part set | Ejector pins, springs, water fittings, seals, hot-runner consumables | Physical, packed with mold |
| Material certificates | Resin batch information for molded-part production runs | PDF (per lot, on request) |
Partner-specific documentation (PPAP-style part submission, first-article inspection reports, resin declarations) can be prepared when your quality system requires it — tell us the format at the quotation stage.
Honest position on certificates: CENTS competes on measured dimensional results, in-house manufacturing and engineering attention — not on a wall of standards logos. If your procurement process requires a specific third-party certification, tell us at the RFQ stage and we will confirm exactly what we can provide, in writing, before you commit tooling budget.
Mold life & maintenance
The cosmetics tooling we delivered was specified for a 1,000,000-shot life and validated at 5,000,000 shots. That difference comes from steel choice, cooling design and maintenance discipline — not from luck.
Replaceable inserts in high-wear areas, accessible water circuits, standard components and clear identification markings on every plate.
Wear parts ship with the mold so your molder does not wait on an international parcel the first time a pin or spring fails.
Remote diagnosis from photos, videos and parameter sheets; repair and refurbishment service at our plant when a tool needs more than adjustment.
