Description

Introduction of barrels:

Barrels are used as an important part for extruder accessory. It is widely used in various industries. Such as XPS extruder, PS granulator, PE pipe extrusion machine. Because of the difference of raw materials, the requirements for the Barrels are different. For example, when some glass fiber materials are extruded, the wear is larger and the gap between the screw and the Barrels is strictly required. the balance of wear resistance and cost is need to be taken full consideration 

We manufacture barrels for co-rotating twin screw extruders ranging from 15.6 mm to 400 mm and over. Our manufacturing specializes in barrels for twin screw extruders and is optimized for flexible order handling.

 Barrel materials:
 

We use different kinds of materials for barrel according to different application.

Normally,there are two main kinds of materials,one is HIP powder tool steel,and the other is special steel.

Solid barrel:

Production Equipment

At present, the company's factory area exceeds 3000 square meters, and an additional 3000 square meters are under planning and design, covering the complete production process of material research and development, main component production, and testing. The company has 6 technical personover 40 workers, and multiple imported production and testing equipment from Taiwan and Germany.

Why Choose Us

1)  Independent research and development of materials and processes can ensure the performance and process of materials to the maximum extent, and greatly prolong the service life compared with ordinary products, while the main supplier in the market only buy raw materials for machining.

2)Independently develop the process of key products, and constantly improve and enhance the old process to achieve the best product performance.For example, we changed  the production process for barrel liner and liner from sintering to spray welding.  Which increased the product service life 3-5 times then normal products.

3)Continuously improving and optimizing product appearance of the composite layer which greatly improved the service life of products.for the separately linner and Barrel Liner, we changed the Composite layer from thin 8 shape to ellipse flat angle shape, which increased the product service life greatly.
