Manufacturing route
How we plan the work
Planificar la repetibilidad
Wall thickness, unsupported sections, threads and flatness requirements are checked against the material’s stiffness and heat response.
Mecanizar y verificar
Workholding, cutting conditions and machining sequence are selected to minimize distortion, burrs and local heat effects.
Aplicar los aprendizajes al siguiente lote
Critical dimensions are evaluated with the stated material, conditioning and reference-temperature assumptions in mind.
El mecanizado de plástico empieza por la condición de servicio
Una revisión de plano y criterios de aceptación claros mantienen controlado cada lote repetido.
Las caras de sellado, ajustes a presión, roscas y superficies visibles deben marcarse como críticas desde el inicio.
Las cantidades, entregas parciales y acabados deben cotizarse juntas.
Part requirements determine the process plan.
Application decisions
Details that make the page actionable
Electrical insulation and instrument fixtures
For insulating fixtures, housings and guides, the decision starts with dielectric needs, temperature and chemical exposure. The drawing should state the resin family, color or grade where relevant, and the dimensions that govern assembly.
Low-friction and wear components
Bushings, guides and wear pads need a material decision that accounts for mating surface, lubrication, load and heat. A polymer selected only for low friction may not hold the required dimensions in service.
Conditioned dimensions for precision interfaces
Where a polymer bore, flatness or position controls function, specify the measurement condition. Temperature and moisture assumptions are essential context for a meaningful tolerance and inspection result.
Engineering decision matrix
What to decide before the RFQ is released
These are the inputs that change process routing, inspection effort and the usefulness of the completed part. They are not universal specifications; the drawing and service environment remain the source of acceptance requirements.
| Decision | What to review | Risk if omitted | Useful RFQ input |
|---|---|---|---|
| Operating condition | Assess temperature, chemicals, electrical duty, moisture, load and sliding contact before selecting a polymer. | Selecting by name or price alone can produce a part that moves, creeps or degrades in service. | Describe the environment, load case, mating material and any dielectric or chemical requirement. |
| Dimensional condition | Agree the material state and reference temperature for fit-critical dimensions. | A part can measure correctly after machining yet differ after moisture uptake or thermal change. | State measurement temperature, conditioning expectation and the dimensions that control function. |
| Geometry and support | Check wall thickness, long unsupported features, bores and threads against material stiffness. | Metal-style geometry can distort during machining or relax after fixturing is released. | Provide section views, datums, flatness needs and insert or thread requirements. |
| Inspection and assembly | Plan measurements and assembly features around polymer behavior rather than a generic tolerance note. | A tight drawing tolerance without condition context produces an ambiguous acceptance result. | Flag fit-critical bores, inserts, mating parts and requested inspection documentation. |
Frequently asked questions
¿Qué cantidades se consideran producción de bajo volumen?
Many engineering polymers can be machined, including ABS, nylon, PEEK, POM, PTFE, polycarbonate and acrylic. The right choice depends on the operating environment and functional load.
¿Puede el primer lote validar la producción?
Critical features can be controlled, but tolerances should reflect the polymer, geometry, conditioning and service temperature. Discuss fit-critical requirements at the drawing review stage.
¿Cómo se mantienen consistentes los pedidos repetidos?
Yes. CNC machining avoids tooling investment and is well suited to prototypes, bridge quantities and low-volume functional components.
