ENGINEERED AROUND YOUR PART
Develop custom automotive plastic components with integrated engineering, mold manufacturing and injection molding. We support conventional and electric vehicle applications, from prototype evaluation to repeat production.
01 / APPLICATIONS
Every location brings a different set of conditions. Start with the component’s function, installation environment and visible surfaces, then translate those needs into a practical material and tooling approach.
01 / INSIDE THE CABIN
Air vents, control panel bezels, buttons, covers and brackets balance appearance with everyday handling. We review visible finish, snap-fit behavior and wall transitions together, looking for sink and warpage risks before the tool design is finalized.
02 / EXPOSED TO THE ELEMENTS
Mirror components, antenna housings, protective covers and grille brackets need a clear definition of exposure and installation loads. Material discussions consider UV and weather resistance, surface expectations and fastening geometry, with validation requirements agreed for the intended environment.
03 / BUILT TO SUPPORT
Wire holders, fuse box components and mounting brackets must suit their surrounding conditions. Heat, contact with media and vibration inform grade selection. For reinforced materials, fiber orientation and shrinkage need attention because they can influence stiffness, dimensions and assembly behavior.
04 / CONNECTING ELECTRIC SYSTEMS
Charging connector housings, terminal retention features, ECU covers and cable holders put emphasis on material grade, electrical requirements and interface dimensions. Insert position, seal contact areas and retention geometry are reviewed against your drawings and the component’s intended assembly.
02 / ONE CONNECTED WORKFLOW
Choose a development route that matches the decisions still to be made. Carrying feedback forward helps align the part, mold and molding process before repeat orders begin.
Use prototype parts to evaluate fit, access and assembly sequence. Record what the prototype can demonstrate and what still needs molded material or production tooling to confirm.
Compare rapid tooling with production tooling using quantity, geometry, material and expected changes. Confirm cavity layout, tool interfaces and the approval stages for the selected route.
Connect injection molding with the required finishing and assembly. Trial feedback establishes agreed settings, appearance references and handling requirements for the next production stage.
A prototype’s appearance does not automatically establish production performance. We distinguish geometry checks from material and process questions, so each stage answers a defined set of questions. If your design is still changing, share the likely revisions early; they may affect how the tooling is arranged and when particular features should be finalized.
03 / DETAILS THAT SHAPE THE RESULT
A bracket or housing is a network of connected features. Our DFM review brings manufacturing questions into the design discussion while changes are easier to make.
Provide mating components or their interface drawings wherever possible. A local feature that looks acceptable in isolation can affect assembly clearance, visible alignment or load transfer. We discuss those relationships alongside manufacturing access, then document the design decisions that need your approval before the next stage.
Review thickness transitions, rib proportions and local mass for filling, cooling and sink risk.
Consider engagement, release, deflection and assembly access in the selected material.
Align draft, parting lines and ejection with function and surfaces that remain visible.
Discuss the illustrated gate tab, flow direction and potential weld line locations against appearance priorities.
Define insert location, support, retention geometry and how position will be checked.
Review dimensional relationships, restraint and reinforcement orientation at mating interfaces.
04 / MATERIAL DECISIONS
Polymer families are a starting point. Final selection depends on the grade’s data, the component’s requirements and any agreed validation. Share an existing specification where one applies.
| Material family | Typical applications | What to confirm |
|---|---|---|
| PP | Covers, trim and wire management | Stiffness, impact behavior, shrinkage and the need for UV stabilization. |
| ABS / PC-ABS | Interior bezels, control surrounds and housings | Surface finish, heat exposure, impact requirements and grade-specific processing. |
| PA | Brackets, clips and functional housings | Moisture conditioning, heat and media exposure; reinforcement effects on dimensions. |
| PBT | Connector and electrical housings | Electrical requirements, moisture handling, reinforcement and the specified grade. |
| POM | Moving features, guides and retention parts | Friction, dimensional needs, chemical exposure and restrictions on bonding or finishing. |
| TPE / TPU | Soft-touch features, flexible covers and interfaces | Hardness, environmental exposure, compression needs and adhesion to the chosen substrate. |
A family name alone cannot define an automotive application. Filled and unfilled grades can behave differently, and colorants or additives may influence processing and performance. Where electrical, flame, weathering or chemical requirements apply, identify the exact specification and acceptance criteria. We use those inputs to guide the material discussion and identify questions that require supplier data or project-specific validation.
05 / APPEARANCE & ASSEMBLY
Bring color, texture and assembly requirements into the initial review. A visible housing may need controlled cosmetic zones, while an internal bracket may prioritize retention and access. Mark critical surfaces and mating parts on the drawing.
Insert molding can integrate specified metal features. Overmolding and two-shot molding can combine material functions where geometry and material compatibility support the approach. We review insert positioning, interface design and adhesion expectations with you before proposing a tooling concept.
06 / AGREED CRITERIA, VISIBLE CHECKPOINTS
Inspection planning follows the part’s requirements. Agree dimensional, appearance and assembly checks, sampling and records for the project, with special attention to features that affect the next operation. Project-agreed deliverables may include a DFM review or report, mold design confirmation, a mold trial record or report, and a dimensional inspection report. Confirm the required documents and approval points for your project.
Confirm drawings, the agreed DFM review or report, and mold design confirmation before the relevant tooling stage.
Review samples and the agreed mold trial record or report against dimensional, appearance and assembly criteria.
Apply the project’s inspection plan, including the agreed dimensional inspection report, and review relevant changes before further production.
Confirm agreed records, quantity, packaging and identification for the shipment.
The drawing and approved references form the basis for review. Where a requirement is ambiguous, we clarify the datum, measurement condition or cosmetic boundary before relying on it for acceptance. Changes to material, geometry or agreed finishing should return to the project review so their effect on fit and appearance can be considered. Explore our facility and quality approach for more context.

EXISTING CATALOG EXAMPLE
This existing catalog example concerns custom injection molds for plastic automotive sensor enclosures. Review housing geometry, mounting interfaces and the fit of mating components during DFM. Material grade, critical dimensions and the acceptance plan are defined from the customer’s drawing for each new project.

EXISTING CATALOG EXAMPLE
This catalog example covers tooling for automotive air-filter components. The part drawing establishes the required frame geometry and interfaces. Mold development connects DFM, machining and assembly with trial review; material, operating conditions and inspection requirements are agreed for the application.

Send 3D files, drawings, quantity, material requirements, finish, mating interfaces and target timing. Highlight critical dimensions and any customer specifications.
We can discuss suitable families and grades against your requirements. Final selection and validation should address the actual operating environment and applicable specifications.
Consider these routes when integrated features or combined material functions support the design. Compatibility, retention, geometry and volume determine whether the approach is practical.
Review prototype feedback, update the design and agree the tooling route. Molded trials then support approval of the part and production requirements.
Identify critical dimensions, cosmetic zones and assembly checks before tooling. Agree inspection methods and sample references as part of the project review.
