Four things buyers care about most — material, accuracy, delivery and cost.
Nitrided and bimetallic options on 38CrMoAlA alloy steel for demanding, high-filler applications.
CNC finishing with controlled clearance and runout, so the set fits and runs smoothly on arrival.
In-house machining and heat treatment keep schedules under our own control, not a subcontractor's.
Direct supply from our workshop — no trading margin, with quotations returned quickly.
We build replacement screw and barrel sets matched to leading injection molding and extruder brands — send us your machine model and we will confirm the fit.
Send a drawing, a machine model or a worn part — we reverse-engineer and manufacture the matching set.
Rough machining, nitriding, finishing and inspection are completed under one roof with documented checks.
Rust-protected, wooden-case packing with clear marking, suitable for sea, air and express shipment.
Model matching, installation guidance and after-sales follow-up from a team that speaks your process.
Certified 38CrMoAlA and bimetallic steel, selected per application.
Turning, boring and milling to near-net shape and dimensions.
Nitriding or bimetallic lining for hardness and wear resistance.
CNC finishing of flights, bores and key tolerances.
Hardness, runout and dimension checks, then export packing.
Shipped with photos and documents; we follow up after installation.
A look at our machining and assembly floor — the sets below were produced and inspected here.
Conical twin sets for PVC pipe, window profile and sheet lines.
Parallel twin barrels built for high-filler and masterbatch runs.
Single screw barrels with stable melting for film and sheet extrusion.
Screw and barrel sets for injection machines, wear-resistant linings available.
Heavy-duty barrels for abrasive recycled materials and high wear.
Single screw sets for bottle and container blow molding applications.
Special screw barrels for XPS foam insulation board production.
Screw barrels for cable sheathing and insulation extrusion lines.
Screws and barrels for WPC profile and board extrusion, with high wear protection.
Choosing the wrong barrel alloy is the single most expensive mistake in screw barrel buying — it costs you twice in downtime and in a second set. This is the comparison we use when we quote.

Different resins destroy barrels in different ways — glass fibre cuts, PVC corrodes, regrind does both. Tell us what you run and we will specify the screw geometry and alloy to match.
Tell us your machine model, drawing or the worn part you need to replace. We will come back with a matching proposal and a quotation.
Fields marked * are required.
Yes. Send us a drawing, the machine model, or the worn part with basic dimensions. We reverse-engineer the geometry and manufacture a matched set, confirming the drawing with you before production.
Standard options include 38CrMoAlA nitrided steel and bimetallic (alloy-lined) barrels. We select the material based on your resin, filler content and expected service life.
Lead time depends on size, material and heat treatment. Because machining is done in-house, we can confirm a realistic schedule with the quotation rather than an estimate.
Each set is rust-protected, fixed inside a fumigation-free wooden case with clear marking, suitable for sea, air and express shipment.
Typical signs: falling output, unstable melt quality, higher drive load, or visible wear at the feed and compression zones. Send us the worn set or its dimensions — we will assess the wear and quote a matched replacement.
Yes. We regularly build sets matched to Engel, Arburg, Haitian, Toshiba, Sumitomo, JSW and other injection brands, as well as KraussMaffei, Bausano, Reifenhäuser and other extruder brands. Send the machine model to confirm compatibility.
