Barrel(Body)

Introduction: Barrels are used as an important part for extruder Accessories

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

15.6-400mm and over

We manufacture barrels for co-rotatingtwin screw extruders ranging from15.6 mm to 400 mm and over.

Our manufacturing specializes in barrels for twin screw extrudersand is optimized for flexible order handling

TYPES OF BARRELS
① Standard for classification: With liner or not
② Standard for classification: Design geometry
BARREL MATERIALS
We use different kinds of materials for barrel according to different application.

ONE IS HIP POWDER TOOL STEEL

THE OTHER IS SPECIAL STEEL

WHY CHOOSE US

1、independent research and development of malenals and processes can ensure the peromance and proces ofmatenials to the maximum exent, and grealy prolong the service life compared with ordinary products, while the main supplier in the market only buy raw materials for machining.
2、indeendenly develop the process ofkey products, and constanly improve and enance the old process to achieve the best product performanc.For example, wechanged the producion process for barrel liner and iner from siniening to spray welding. Which increased the produc senvice lile 3-5 times then normal produclis
① The liner alloy layer :old sintering process
② Characteristics and advantages of the newspraywelding process: the product is better in dense, thehardness can reach more than 56 degrees, the servicelife of the product is 3-5 times that of the sinteringprocess, low cost, less waste.

3、Continuously improving and optimizing product apearance ofthe composite layer , which greatly improved the serice fe of products.for the separately inner andBarrel Liner, we changed the Composite layer from thin 8 shape to elipse lat angle shape, which increased the product service life greaty.
