Aiming at different plastic products the screw can be chosen from: General type, pin type, barrier type, separation type, and gas-exhausting type, etc.
1.We are a professional company specialized in manufacturing many types of screw, the barrel can be applied on all types of injection moulding machine,rubber hot-feeding extruder, rubber cold-feeding extruder, pin barrel cold feed extruder, plastic extruder with different specifications.
2.The models of screw include:
Variable pitch and variable depth, variable pitch and equal depth, variable depth and equal pitch, and equal depth and pitch.
Groove multi-die type, composite type, mixing type and separating type.
3. The material of screw: manufactured with high-quality nitro alloy steel, applying the method of hardening and tempering and nitriding, thus it enjoys the characteristics of long working life, wear resistance, and anti corrosion. Besides, the technique of hard alloy spraying or chrome plating can be used on the working surface of screw, which will make it have better using effectiveness.
Ningbo Superior Machinery and over 30-year-old factory with ISO 9001:2008 certificated, manufacturing screws, barrels for injection and extrusion processing.
Specifications of our Ni-based bimetallic barrel:
Basic Material for body: superior pre-hardening material 4140
Alloy powder: Nickle-based self-melting alloy powder from American Wall Colmonoy Corporation
Processing: vacuum sintering cladding ( we're the first and unique Chinese factory applying this technology to barrel production since 2009!)
Hardness: 56-60 HRC
Service life: 3~6 times than bimetallic barrels processed by high temperature centrifugal casting
Application: halogen-free plastic, the high abrasion, corrosion materials adding high fibre, carbon fiber, mineral fiber, ceramic, magnetic powder, metal powder etc.
Advantage: more stable molecular structure, higher density of the alloy power than common bimetallic barrels.
Deck screws are screws specifically designed for use in outdoor decking projects. They are usually corrosion-resistant to withstand exposure to the elements. The "inch" specification likely refers to the length of the screws.
Wooden Drum Barrel
The typical specifications of a wooden drum barrel include a main material of oak wood, measured in gallons or liters (e.g., 5, 15, 30, 55 gallons), a metal hoop or band frame (usually steel), top and bottom closed with wooden heads, and a possible bung for sealing. The weight, surface finish, and other details may vary depending on the specific use case.

The bimetallic barrel for single screw is a kind of barrel moulding 2-3mm thick alloy coat on the barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided cylinder. Bimetal has more obvious advantages when processing special plastics to enhance the abrasion life, such as engineering plastic, fluorine plastics, PPO and etc.
The company product's single/twin screw, uses special alloy powders being sprayed and welded on the screw's ridge, and uses different alloys and welding methods for the screw of different functions.
