Non-standard plate sizes, offset guide pillars, stepped pockets, non-standard cooling layouts — the jobs standard catalogues refuse. We review your drawing in 24 hours, quote the tolerance we can hold, and ship with the CMM report that proves it.
A custom base fails in one of two ways: the geometry cannot be machined as drawn, or it can but moves after machining. We deal with both before the steel is cut.
Plate sizes outside the standard table, asymmetric layouts, cut-outs for slides and lifters, extended clamping edges for oversized platen.
Offset guide pillars, stepped parting lines, raised pads, unequal plate thickness — machined from one setup where possible to keep alignment.
Plates over 150 mm are roughed, stress-relieved, then finished, so flatness survives the first 10,000 cycles instead of the first week.
Deep-hole drilling to Ø30 × 1200 mm, baffles, hot-runner manifold pockets and wiring channels machined into the frame.
Insert pockets held to ±0.005 mm with matched corner radii, so the insert sits without shimming or hand fitting.
Prototype single sets and annual frame agreements with dimension records kept, so a repeat order matches the first one exactly.
Custom work is judged on the fits that matter: guide-pillar bores, insert pockets, plate flatness and squareness. These are the values we inspect and report.
| Item | Range / Standard | Notes |
|---|---|---|
| Frame size | Up to 2000 × 1300 × 800 mm machining envelope | Larger frames sectioned and assembled, joint faces machined after assembly |
| General machining | ±0.01 mm | Non-fitting surfaces, clearances, reliefs |
| Precision fits | ±0.005 mm | Insert pockets, guide-pillar bores, locating seats |
| Coordinate grinding | ±0.001 mm | Guide-bush bores, precision bore repair |
| Flatness | ≤0.02 mm per 300 mm after stress relief | Measured on granite plate |
| Squareness | ≤0.01 mm per 100 mm between adjacent faces | CMM verified |
| Surface roughness | Ra 0.4 – 1.6 µm | Chosen by function, not by default |
| Materials | 45#, 40Cr, P20, 718H, S136, NAK80, S50C, H13 for die casting | Mill certificate per heat number |
| Inspection | First-article + final CMM, report in PDF with the shipment | Dimensional record kept for repeat orders |
Values are our routine capability, not a marketing ceiling. Anything outside the range goes through a technical review first — we confirm feasibility before quoting, and we do not promise what the machines cannot hold.
Every custom job is a small project. The sequence below is what keeps a 6-week mould build from slipping because of a 2 mm pocket error.
We check wall thickness, bore depths against drill reach, corner radii against cutter size, and flag anything that would need EDM instead of milling. You get the marked-up drawing back.
24 hoursThe quote lists dimensions we will hold, the ones we cannot, and the price difference if you need the tighter class. No hidden "as per drawing".
1 dayMaterial cut with allowance, roughed, stress-relieved in furnace, then checked for movement before finish machining starts.
3–6 daysBores, pockets and faces finished; insert pockets trial-fitted with the actual insert where supplied.
4–10 daysFinal inspection on the CMM, report compared against the first article, crate packed with the dimensional record inside.
1–2 daysSend the drawing even if it is not finished — we would rather flag a problem at sketch stage than quote a base that cannot be machined. Review is free, and it is the fastest part of the project.
Straight answers to the questions buyers actually ask before the first order.
Nothing on this page replaces looking at your actual geometry. Send what you have and we will tell you what is straightforward, what is expensive, and what we would change.
