Molded Plastic Parts for Instruments & Meters
Handheld cases, display bezels, sensor covers and small functional parts with attention to location, access and fit.
Application-led design · Material review · Sample approval
Keep the important interfaces easy to define.
An instrument housing must locate its internal components while keeping displays, probes and controls accessible. Review the enclosure, operating controls and fixing features together so the final assembly has a clear reference.
Display & control layout
Align apertures, button regions and access points with the internal component layout.
Assembly features
Define board supports, probe or sensor interfaces and the mating dimensions that matter.
Plastic components for instruments & meters.
Explore typical component families and the interfaces to consider before tooling.
Handheld Detector Cases
Coordinate the display window, control opening and handheld fit.
Instrument Front Covers
Review viewing apertures and the shape of the mating enclosure.
Sensor Covers
Define the sensing region, cover alignment and installation details.
Connector Interfaces
Coordinate contact positions and access around the instrument assembly.
Choose a route around the component.
Connect the part geometry, selected resin and target quantity with the manufacturing services it needs.
Plastic Injection Molding
Custom plastic parts built around your design. A connected route from material selection and production tooling to approved samples and repeatable supply.
Insert Injection Molding
Bring metal strength and plastic design freedom together. Mold threaded inserts, pins and contacts into a component designed for its final assembly.
Surface Finishing
Give your plastic component its intended appearance. Coordinate selected surface treatments, color and marking with the resin, part design and final application.
Start with the job the material must do.
Use the application, environment and assembly requirements to compare candidate resins. Final grade selection follows the complete component brief.
An opaque thermoplastic commonly considered for detailed housings and covers where appearance, moldability and everyday impact performance need to work together.
Polycarbonate is considered for clear covers and technical housings where transparency or impact performance guides the brief. Clear, translucent and opaque grades serve different requirements.
POM is used for functional parts such as gears, bushings and small mechanical components where sliding behavior, stiffness and dimensional fit matter.
Turn the application brief into sample checks.
Use drawings, mating references and agreed acceptance points to review the component before regular production.
01 / Display alignment
Mark the dimensions locating screens, indicators and control apertures.
02 / Sensor & probe interfaces
Provide the mating references and any required clearances.
03 / Handling & legibility
Review the grip, legends and visible surface on an assembled sample.
Quality checks, connected to your drawing.
A useful inspection plan follows the component through incoming material, production and final release. Define the checks around the features your product depends on.
Start with the material brief.
Confirm the specified resin and the incoming requirements that matter to the component before production.
Check the part as it takes shape.
Review the agreed dimensions, molded features and visible surfaces during the production route.
Use a clear release reference.
Compare the finished parts with the drawing, approved sample and agreed inspection points before packing.
Plan protection around the part.
Surface finish, component geometry and the assembly destination all inform the packing brief.
Plan the final handoff around your parts.
Include packaging and delivery requirements in the project brief so the finished components reach the next stage ready for handling.
Protect the visible surfaces
Separate display bezels and small instrument parts to protect their exposed and locating features.
Keep components identifiable
Agree on part grouping, quantity per pack and any labeling or assembly-set requirements.
Confirm the delivery brief
Share the destination, shipment quantity and handling needs so packing and dispatch can be coordinated.
