Selection Guide

Not Sure Which One You Need?

Answer three questions and the right category is usually clear.

1

What machine do you run?

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.

2

What material do you 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.

3

What problem are you solving?

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 Options

Materials & Surface Treatment

Material and treatment are selected by the resin, filler content and expected service life — not by price alone.

NITRIDED

38CrMoAlA Nitrided

Gas nitrided to HV 900–1100. The standard choice for general-purpose resin.

BIMETALLIC

Bimetallic Alloy Lining

2–5 mm alloy layer for abrasive, filled, recycled or corrosive material.

ALLOY

42CrMo / 40Cr

Through-hardened alloy steel for higher torque and shock loads.

STAINLESS

Stainless Steel

For PVC, fluoropolymers and food or medical applications.

WC

Tungsten Carbide

Maximum abrasion resistance for heavily glass-filled compounds.

HARDFACE

Hardfaced Flights

Alloy spray-welded onto screw flights for extended wear life.

Manufacturing

From Drawing to Finished Set

1

Drawing or Sample

Send a drawing, machine model, or the worn part — we reverse-engineer and confirm geometry.

2

Material Selection

Base steel and surface treatment chosen for your resin, filler and service life target.

3

Precision Machining

CNC turning, boring and thread grinding with allowance for heat treatment.

4

Heat Treatment

Nitriding, bimetallic casting or hardfacing, with hardness verified on coupons.

5

Inspection & Packing

Dimensional and clearance checks, rust protection, wooden case packing.

6

Delivery & Support

On-time shipping and fitting guidance for your maintenance team.

FAQ

Frequently Asked Questions

I am not sure which category my screw barrel belongs to.

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.

Can you build a screw barrel without a drawing?

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.

Do you supply spare parts as well as complete sets?

Yes — screws, barrel liners, segmented elements, planet rolls and other wear parts, matched to your existing machine.

What materials and treatments are available?

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.

Which machine brands do you cover?

Engel, Arburg, Boy, Demag, JSW, Toshiba, Sumitomo, Haitian and LG for injection; KraussMaffei, Bausano, Reifenhäuser, Leistritz, Cincinnati, Maplan and AMUT for extrusion, among others.

How is the set packed for export?

Rust-protected and fixed inside a wooden case with clear marking, suitable for sea, air and express shipment.
