What is PCP DIE PIN
The progressive cavity pump stator mold core is the core mold of the vulcanized stator rubber cavity, which directly determines the sealing performance and conveying efficiency of the progressive cavity pump. Its geometric characteristics are complex spiral cavity (lead/pitch accuracy requirement ± 0.02mm), and commonly used materials include alloy steel (Cr12MoV) and superalloy (Inconel 718). Common risks: poor stator sealing due to processing deformation, insufficient accuracy causing pump body leakage, and blockage of cooling holes affecting the vulcanization quality.
PCP DIE PIN Whirling Core Pain Point
There are three major bottlenecks in the processing of stator mold cores in traditional vertical machining centers:
- Low efficiency: single piece processing takes 8-10 hours, which cannot meet the needs of mass production;
- Complex spiral structure is difficult to handle: it cannot be adapted to large-lead (≥100mm) cavity processing, resulting in customer order delays

Key points of the sub-link
- Rough machining: Adopt integrated high-strength bed (40% rigidity increase) + 55° dovetail double guide rail, with carbide tools, quickly remove the margin. Parameters: Feed speed X-axis 5m/min, Z-axis 3m/min to avoid deformation.
- Finishing: three-axis linkage (C/X/Z axis) + CAM optimized tool path, spiral cavity pass adopts contour strategy, positioning accuracy ≤ 0.01mm. Key equipment: PH80-2000 feed shaft precision ball screw.
- Surface treatment: automatic polishing system, control Ra ≤ 0.4μm, improve the wear resistance of the mold core.
