Joiner Machinery provides professional screw repair services for
Japanese 335 polyolefin extrusion pelletizers. To address issues
such as reduced production efficiency and unstable product quality
caused by screw wear, we adopt a standardized full-process
workflow. Through core technologies including precision inspection,
threaded element restoration, mandrel straightening, additive
repair at seal positions, and high-hardness wear-resistant layer
rebuilding, we restore the screw to its original dimensions and
performance. After repair, each screw undergoes full-size 3D
inspection and meshing test verification. Our service greatly
extends service life, saves enterprises up to 60% of replacement
costs, achieves cost reduction, efficiency improvement and rapid
production recovery, and provides stable and reliable equipment
support for extrusion and pelletizing production lines.
