Machining Challenges We Solve
Strict control is required during the manufacturing process, especially for reinforced PEEK, thin-walled parts, and high-precision components. Our manufacturing process effectively addresses the following common challenges:
Controlled Machining for Demanding PEEK Components
From reinforced grades to thin-wall and tight-tolerance components, we coordinate machining parameters, tooling, fixturing, and inspection to address common manufacturing challenges.
Heat & Deformation
We optimize cutting conditions and machining parameters to minimize heat-related deformation and maintain dimensional stability.
Tool Wear
Glass-filled and carbon-filled can accelerate tool wear. We select suitable tooling and cutting conditions according to the material grade and part geometry.
Tight Tolerances
For high-precision parts, machining, fixturing, and inspection are coordinated to maintain critical dimensions and tolerances.
Complex Geometries
We review complex, thin-wall, and intricate components before production to determine the most suitable machining approach.
PEEK Quality Control & Inspection
From material verification and machining to final inspection, we strictly control the quality of the entire manufacturing process. Critical dimensions, tolerances, surface requirements, and part consistency are all checked according to your specifications.
Dimensional Inspection
Part dimensions are checked against drawing requirements.
Critical Tolerance Inspection
Critical dimensions and tolerances receive focused inspection.
First Article Inspection (FAI)
First articles can be inspected according to defined requirements.
Surface Inspection
Surface requirements are checked according to specifications.
