Delrin Injection Molding
Custom Delrin (POM) injection molding for gears, bushings, and low-friction mechanical parts.
Delrin Injection Molding Service
Injection molding for Delrin (POM) parts, supporting DFM review, material grade selection, tooling, sampling, and production.

Why Choose Kemal for Delrin Injection Molding
Delrin Part Fit
Delrin (POM) molding for gears, bushings, wear components, and snap-fit parts where low friction and stable fit are required. Designs are reviewed based on how the part functions in the assembly.
DFM Output at Quote Stage
DFM feedback is provided before tooling to review wall balance, ribs, draft, and gate/vent approach. The goal is to reduce shrinkage/warpage risk and avoid weak weld-line locations on functional features.
Tooling Decisions for Functional Features
Tooling strategy is aligned to feature control, including venting, ejection, and cavity-to-cavity consistency when required. This helps reduce burn marks, cosmetic defects on contact surfaces, and dimensional drift across runs.
Process Window for Stability
Process settings are managed around dimensional stability and repeatability for Delrin parts. Key variables (mold temperature, cooling, packing profile, and residence-time risk) are reviewed during sampling and adjusted based on CTQ requirements.
CTQ Validation & Inspection Options
T1 sampling is used to confirm CTQ dimensions and assembly fit against the drawing. Dimensional reports, CMM measurement, and material documentation are available when specified.
Grade Selection for Performance Targets
Delrin/POM grade options are reviewed based on friction behavior, wear targets, stiffness, and environmental exposure. Homopolymer vs selected copolymer formulations can be evaluated during quoting to match functional requirements.
Typical Delrin Parts We Mold
Precision Gears & Gear Trains
Delrin gears and gear sets for repeatable motion transfer where tooth form and concentricity affect fit and noise.
Bushings & Sleeve Bearings
Low-friction Delrin bushings and sleeves for shafts and pivots, supporting stable fit and wear performance.
Wear Pads & Sliding Guides
Wear pads and sliding guides for continuous contact surfaces in automation and conveying assemblies.
Snap-Fits, Clips & Latching Parts
Functional snap-fits and clips where controlled deflection and consistent engagement are required.
Cams, Levers & Linkage Components
Cams and linkage parts for motion conversion, where contact surfaces and wear behavior affect cycle life.
Rollers, Spacers & Pivot Components
Rollers, spacers, and pivot parts used in repeated motion cycles, often sensitive to tolerance and wear.
