An injection molding machine uses an injection screw barrel. An extrusion line uses an extruder, parallel twin, conical twin, rubber or planetary barrel depending on the process.
Clean resin runs well on nitrided steel. Glass-filled, mineral-filled, recycled or flame-retardant material needs a bimetallic screw barrel for acceptable service life.
Falling output and unstable melt quality usually mean wear. Burning and decomposition point to geometry or temperature control. Describe the symptom and we diagnose from there.
Material and treatment are selected by the resin, filler content and expected service life — not by price alone.
Gas nitrided to HV 900–1100. The standard choice for general-purpose resin.
2–5 mm alloy layer for abrasive, filled, recycled or corrosive material.
Through-hardened alloy steel for higher torque and shock loads.
For PVC, fluoropolymers and food or medical applications.
Maximum abrasion resistance for heavily glass-filled compounds.
Alloy spray-welded onto screw flights for extended wear life.
Send a drawing, machine model, or the worn part — we reverse-engineer and confirm geometry.
Base steel and surface treatment chosen for your resin, filler and service life target.
CNC turning, boring and thread grinding with allowance for heat treatment.
Nitriding, bimetallic casting or hardfacing, with hardness verified on coupons.
Dimensional and clearance checks, rust protection, wooden case packing.
On-time shipping and fitting guidance for your maintenance team.
OEM screw barrel supply for injection molding machine and extruder builders.
Replacement sets for local aftermarket supply, built to your customers' worn samples.
Pipe, profile, sheet, film and compounding plants running production lines daily.

Tell us the machine type — injection molding machine or extrusion line — plus the resin and screw diameter, and we will point you to the right category. You can also send a photo of the worn part.
Yes. Send the worn screw and barrel, or the machine model with basic dimensions. We reverse-engineer the geometry and send a confirmation drawing for approval before production.
Yes — screws, barrel liners, segmented elements, planet rolls and other wear parts, matched to your existing machine.
Nitrided 38CrMoAlA, bimetallic alloy lining (2–5 mm), 42CrMo, stainless steel, tungsten carbide and hardfaced flights. Selection depends on your resin, filler and expected service life.
Engel, Arburg, Boy, Demag, JSW, Toshiba, Sumitomo, Haitian and LG for injection; KraussMaffei, Bausano, Reifenhäuser, Leistritz, Cincinnati, Maplan and AMUT for extrusion, among others.
Rust-protected and fixed inside a wooden case with clear marking, suitable for sea, air and express shipment.
