Which plastic is best for replacing a worn metal machine part?

It depends on the load and environment. HDPE suits gears, bushings, and rollers where strength and dimensional stability matter. UHMWPE is the pick for wear strips and guides where low friction and abrasion resistance are critical. Our team can recommend a grade once we know what the part is doing.

Can you machine a replacement part from a sample I bring in?

Possibly, drop the worn or broken part into the workshop and we will measure it, identify the material if you do not know it, and machine an equivalent (or an upgrade in a better plastic). For complex internal features we may ask for a drawing or photograph of the original installed assembly.

What tolerances do you hold on machined plastic parts?

Standard work is held to +/-0.2mm, which is fine for guides, spacers, and most wear components. Where parts need to fit closely to metal shafts or bearings we can hold tighter, around +/-0.1mm, with a quick QA check on each piece before dispatch.

CNC Routed Architectural Lettering

Large-format dimensional letters CNC routed from aluminium composite panel, foamed PVC, HDPE, and thick acrylic for building facades, monument signs, and exterior wayfinding. Laser and CNC cutting is restricted by thickness and material rather than size, so we can produce letters in a wide range of sizes with straight machined edges. Built for sign companies and shopfitters needing big, weather-stable letters with straight machined edges.

Signage

Full-size sign panels and sign trays CNC routed from aluminium composite panel, foamed PVC, and HDPE up to 2440mm x 1220mm. We v-groove ACP for folded sign trays and fascia boxes, machine LED cut-outs and rebates for illuminated panels, and rout vehicle signage substrates to size. This is the workhorse process for shopfront fascias, directory boards, and exterior signage that needs to come off a single full sheet.

CNC Machined HDPE Parts

Machined HDPE components routed to your drawings or sample part: wear strips, machine guards, food-contact surfaces, livestock panels, tank lids, and marine fender pads. We work from CAD files or a worn original, holding tolerances to +/-0.2mm and including drilling, pocketing, and chamfering in the same operation. This is the route to take when you need finished parts, not just rectangular sheet.

CNC Machined Polycarbonate Parts

Machined polycarbonate components routed to your drawings or sample, including machine windows, safety guards, glazing panels with mounting cut-outs, and complex shaped profiles. We use single-flute upcut plastic tooling and tuned feed rates to produce cold-cut crack-free edges that will not stress-craze in service. Built for engineers, fabricators, and equipment manufacturers needing finished parts rather than blank sheet.

CNC Routed Aluminium Composite Panel

Aluminium composite panel CNC routed to flat shapes with machined edges. We cut panels with curves, slots, and cut-outs from full sheets. We do not v-groove, bend, or fabricate this material, we simply cut flat shapes to your drawings.
