Tooling and molding for your repeat plastic parts.
YOUR GRADE. YOUR MOTION. YOUR FIT.
POM / Acetal for Your Custom Parts
Review your polymer family, stock or resin, and finished-part requirements. For your POM machining services enquiry, plan CNC machining or molding around your load, motion and assembly fit.
Material availability and process scope confirmed for your drawing.
Grade & FamilyConfirm POM-C or POM-H.
Stock or ResinIdentify your actual product.
Wear & Finished FitDefine load, motion and interfaces.
Records & ApprovalAgree the evidence you need.
Two Material Families. Two Purchasing Routes.
Specify both the polymer family and the form you are buying.
CNC Stock: Sheet, Rod or Tube
TECAFORM AH natural: POM-C. TECAFORM AD natural: POM-H. Confirm the stock product, color and lot before cutting your acetal machined parts.
Molding Resin: Full Grade + Color
Delrin 500P: POM-H resin. DURACON M90-44: POM-C resin. Define the exact formulation and approve a molded sample for your application.
Delrin is a brand, not a name for every POM. A resin datasheet does not identify unspecified CNC stock.

Resolve 6 Fit & Wear Questions Before Production
Review actual machining requirements together with your geometry and working conditions.
Plan Balanced Removal Around Your Datums
To review acetal warping and acetal dimensional stability, discuss initial stock, support and removal sequence. Material removal and clamping can change the part shape as residual stresses redistribute. Define whether free-state or installed dimensions are accepted.
01 · Stock form02 · Datums & support03 · Removal balance04 · Final state
Keep Your Thin Features Supported
Review wall transitions, unsupported spans and the features that must retain assembly fit after release. Specify accepted edge breaks and allowable burrs on critical interfaces.
01 · Wall transitions02 · Support03 · Accepted edges04 · Inspection
Review Both Sides of Your Sliding Contact
For an acetal press fit or sliding interface, agree conditions before choosing a wear-modified grade. Acetal machining tolerances need the actual stock, feature size and measurement state.
01 · Load & speed02 · Counterface & finish03 · Lubrication & heat04 · Acceptance method
Agree Your Working and Measuring Temperatures
Account for acetal thermal expansion: a room-temperature check does not define a hot or cold running clearance. Review the mating material and operating range.
01 · Temperature range02 · Mating material03 · Clearance04 · Measurement state
Choose an Assembly You Can Validate
POM is difficult to bond or paint. Review mechanical retention, supplier-approved preparation and validation of the actual joint.
01 · Joint design02 · Surface preparation03 · Actual exposure04 · Joint validation
Specify the Contact Face, Not Just a Finish Name
Agree tool marks, burrs, cosmetic faces and sliding lands. Coatings and laser marking need product-specific trials.

Answers Before You Specify
What information is required for an acetal machining quote?
For an acetal machining quote or POM injection molding quote, send CAD and controlled drawing, full product name and color, quantities, critical fits, service conditions, finish and inspection requirements.
When should acetal gears be machined instead of molded?
For your custom acetal gears, compare quantity, tooling, geometry and the sample purpose. Machining can evaluate fit from specified stock; production resin, molded geometry and functional tests need separate approval.
How should press fits be specified for acetal bushings?
When comparing an acetal bushings manufacturer, provide both mating materials, sizes, loads, temperature range and accepted assembly condition. Agree interference and inspection for the actual joint; do not apply one universal allowance.
How should acetal parts be conditioned before inspection?
Agree the actual material, temperature, time and free-state or installed measurement condition with the drawing authority. Record these conditions with critical dimensions instead of assuming one universal conditioning time.
Is every acetal Delrin?
No. POM is a polymer family; Delrin is a brand of acetal homopolymer. Confirm the manufacturer, complete grade, color and product form.
Can POM-C replace POM-H?
Not automatically. Compare the exact products, stock or resin route, environment, geometry and required acceptance. Obtain drawing-authority approval before substitution.
Does a resin datasheet identify my CNC stock?
No. Specify the actual sheet, rod or tube product, manufacturer, color and lot. A molding-resin reference does not identify unspecified stock.
Can POM be glued or painted?
POM is difficult to bond and paint. Review mechanical retention or a qualified surface and adhesive system, then validate the actual joint under its intended exposure.
What drives my POM part cost?
Material product, usable stock, tooling, geometry, quantities, critical fits, inspection and secondary work affect your quotation. Compare the same drawing revision and acceptance scope.
Material references: Ensinger · Delrin · Polyplastics · Celanese. Confirm current documents for your exact product and form. Availability and acceptance requirements are project-specific.
