Counter Rotating Twin Barrel
Ho Hsing's production of twin-screw barrels requires not only advanced design and engineering analysis, but also high-performance materials, precision machining, and strict quality control. Every barrel undergoes high-precision CNC machining, thorough inspection, and heat treatment to ensure consistent quality and performance. With our precise manufacturing process, the clearance between the screw and barrel remains uniform, preventing uneven wear.
Our Counter rotating twin barrel are integrally formed, offering a more cost-effective option compared to Twin barrel elements. These are commonly used in the processing of PVC materials.
We also offer two-section twin-screw barrels. The key difference lies in the high-wear areas, where Sinter Bimetallic liners are used. When wear occurs, only the worn section needs to be replaced-similar to the Twin barrel elementsthus improving maintainability and reducing costs over time.
Production Process
From the initial order, understanding customer needs, then to design and production, we will strictly control every step and ensure to meet the customer's usage conditions and customer production environment requirements.
We also consider any special demands of our customers such as spray welding on the OD of the screw to enhance wear resistance.
In terms of design discussion, we will also stand as a professional perspective to help you prevent the problems that may occur in the future.
Product Features
- Customization: Understanding the different needs of each customer, we provide customized services from design to manufacturing, we can precisely custom-made the product dimensions, materials and features to meet customers' different needs and ensure optimal machining performance.
- Precision: We used advanced manufacturing equipment and technology, also we have 3D coordinate measuring equipment to make sure each product has high precision and consistency.
- Life Span: Our product used high quality material and heat treatment, also we can design the screw according to customer's bad production environment. Through special treatment, provide outstanding corrosion resistance and abrasion resistance, extended product life, customer will not only no worry about the production capacity but also decrease the maintain cost of equipment.
- Total Solution: During the production process, our technical team could directly discuss with the machinist and solve customer's problem to achieve customer's demand. From the material chosen to production, we have over 30years experience and professional consult to ensure production work without any problem.
