High-Quality Extruded Bar Suppliers & Products

Extruded PA66 is processed through screw plasticization under elevated shear rates, making it optimal for small-to-medium cross sections where high rigidity and fatigue endurance are needed. Cast MC (Monomer Casting) nylon uses direct chemical polymerization in low-pressure molds. MC nylon boasts higher molecular weight, superior crystalline uniformity, minimal internal stress, and superior wear characteristics, enabling oversized rod and block production up to 1000mm in diameter without risk of centerline porosity.

Centerline porosity in POM (polyoxymethylene) is typically caused by volumetric shrinkage as the outer shell solidifies faster than the molten core. SHUNDA mitigates this through calibrated die-head backpressure, reduced pull-rates, and multi-zone liquid cooling tanks that equalize thermal dissipation from core to perimeter, followed by full stress-relieving annealing cycles.

Yes. Beyond supplying standard 1000mm and 2000mm extruded bars, our facility operates high-precision multi-axis CNC lathes, turning centers, and 5-axis routers. Clients submit 2D drawings (DWG, PDF) or 3D STEP files to receive turnkey machined parts inspected via coordinate measuring machines (CMM) before international shipment.

Standard inventory bar diameters (15mm to 100mm) ship within 3 to 7 business days. Custom polymer formulations, special colors, or custom tooling profiles typically require 10 to 18 days. We maintain flexible minimum order quantities (MOQs) starting from single-box prototype orders up to multi-container orders, supporting FOB, CIF, CFR, and DDP terms with direct dispatch via Tianjin or Qingdao ports.
