How long is the service life of bimetallic screw element?

For high glass fiber / high filler formulas, service life can reach 18000 to 35000 working hours, much longer than ordinary nitrided elements.

What surface alloy options do you offer for screw elements?

Standard tungsten carbide bimetallic alloy for high wear resistance; corrosion-resistant nickel-based alloy for processing acid additives and corrosive flame retardants.

Why modular screw element design saves production cost?

Only the severely worn kneading/mixing elements need to be replaced instead of the whole screw shaft, which greatly reduces spare parts replacement cost and downtime loss.

Key features

Full bimetallic alloy cladding on working surface, excellent anti-wear and anti-corrosion performance, greatly extend service life.

Multiple functional element types available: conveying elements, kneading blocks, mixing elements, barrier elements, vent elements to meet different plastic compounding processes.

Precision CNC machining, strict tolerance control, perfect clearance matching with twin screw barrel, low material leakage and stable extrusion pressure.

High strength substrate steel with uniform alloy layer, not easy to peel off under high temperature, high torque and high filler abrasion environment.

Specially designed for processing glass fiber reinforced plastics, mineral filled masterbatch, flame retardant, biodegradable plastics and corrosive modified materials.

Modular design, customers can freely assemble element combination according to formula requirements; only replace worn single element to cut maintenance cost.

Complete supporting bimetallic barrel sections supplied together, one-stop spare parts solution for twin screw extruder.

Customizable outer diameter, length, thread pitch, kneading angle and alloy formula based on extruder model and production formulas.

Stable plasticizing, uniform mixing, low shear, effectively avoid material degradation and yellowing during extrusion.

Compatible with most parallel twin screw extruders from European, Chinese and international mainstream brands.

AI-Powered supplier vetting

SummaryBloom (Suzhou) Materials Co., Ltd. is identified as a China-based trading company in Jiangsu, focused on alloy materials, spot-welding parts, and extruder machined parts. It reports ISO 9001 certification, three production lines, broad export coverage, self-operated import/export rights, and export activity since 2018. Its stated product scope includes KCF guide pins and sleeves, welding electrodes, and twin-screw extruder components. The supplier describes imported raw materials, specialized processing, and customization inquiries, but provides limited evidence regarding after-sales service, financial credibility, and innovation. Production capacity is documented, while the available trade records show transactions with Mexican buyers for ceramic centering products, blades, and heating resistors.

CertificationsThe supplier reports holding ISO 9001 certification. This is explicit evidence of a certified quality-management system, although the provided information does not include certificate scope, issuer, or validity details.

Production capacityThe supplier reports three production lines and product coverage spanning welding electrodes, KCF guide pins and sleeves, and twin-screw extruder components. It also states a peak-season fulfillment time of two to three months, providing evidence of operating capacity, though the slices do not verify equipment scale, actual output volume, or manufacturing ownership.

Customization capabilityThe supplier explicitly invites customized orders and offers machined parts for twin-screw extruders alongside specialized KCF and welding-related components. This supports the existence of customization capability, although no examples of customized projects, engineering workflow, or minimum-order requirements are given.

Client casesTrade records show transactions with Mexican buyers, including COMERCIAL CALIBRATION TOOLS SA DE CV and DEM WELDING S DE RL DE CV, for blades, ceramic centering products, and heating resistors. These records provide identifiable customer and product evidence, but they are limited in number and do not document customer satisfaction, repeat-order outcomes, or project performance.

Product Q&A

Q:What is bimetallic screw element used for?

It is mainly used for twin screw extrusion lines processing abrasive or corrosive materials, such as glass fiber modified plastics, high mineral filled masterbatch, flame retardant plastic, PLA/PBAT biodegradable plastics and PVC compounding.

Q:What is the difference between bimetallic element and nitrided element?

Nitrided element is low cost for ordinary non-abrasive plastics with short service life. Bimetallic element has thick wear-resistant alloy layer, 3 to 5 times longer service life under high-filler harsh working conditions.

Q:Can you produce customized screw elements according to drawings or samples?

Yes. We accept OEM customization based on your extruder drawing, sample element, screw diameter, center distance and process requirements.

Q:Do you supply matched bimetallic barrel together with screw elements?

Absolutely. We provide complete supporting bimetallic barrel segments and various screw elements as full extruder spare parts package.

Q:What types of screw elements can you manufacture?

Conveying elements, kneading blocks, mixing elements, barrier elements, reverse elements, vent devolatilization elements, side feeding special elements.
