for Electronics
Custom enclosures, mounting components, thermal plates and test fixture components—made to your drawings and assembly requirements.
GPT Precision supplies metal and engineering-plastic parts for electronics prototypes and low- to medium-volume production. We review critical fits, functional surfaces, finishing and inspection requirements against your current drawings.
零件 & applications
Components for Electronic Assemblies
From PCB mounting positions to connector access, each feature has a role in the finished assembly. CNC铣削, turning and 5-axis machining support custom geometry defined by your drawings.
Brackets & Mounting Parts
Sensor brackets, camera mounts, plates and spacers with drawing-defined locating features and hole patterns.
Heat Sinks & Thermal Plates
Machined thermal components with specified contact-face flatness, surface finish and mounting geometry.
Test Fixture Components
Locating plates, nests and supports with defined datums, contact points and replaceable features.
Engineering priorities
Define the Interfaces That Matter
Electrical and thermal performance depend on the complete design and validation requirements.
配合 & 对准
Define PCB mounting positions, connector clearances, threaded features and mating faces, with the datums, tolerances and mating-part references that control assembly.
Functional Contact Surfaces
Mark grounding areas, shielding contacts and thermal faces. Specify flatness, finish and masking boundaries, including coating exclusions and acceptance criteria before or after finishing.
Cosmetic Finish
Identify visible faces, texture direction and acceptable machining marks. Supply a finish reference or visual acceptance standard.
Dimensional Verification
CMM, optical measurement and dimensional gauges are available. Agree critical dimensions, 基准点, sampling and reporting scope during quotation.
材料 & Surface Finishes
材料
铝, stainless steel, copper and brass, along with engineering plastics such as POM, polycarbonate and PMMA.
Specific grades are reviewed against the drawing, including contact-surface, appearance and finishing requirements.
Surface Finishes
Options can include anodizing, bead blasting, brushing, 抛光, plating and passivation, subject to material and process compatibility.
Define the required treatment for each surface, together with masking, cleanliness and handling requirements.
Specify surfaces that must remain uncoated, along with critical dimensions that apply after finishing.
From Prototype to Repeat Production
Prototype Review
Provide the current drawing revision and identify what you need to evaluate: assembly fit, connector access or appearance. Highlight open design questions so quotation assumptions are clear.
Repeat Production
Provide the released drawing, approved finish reference and inspection scope. Highlight changes from the previous revision or sample, including packaging requirements.
Lead time is reviewed against the drawings, materials, quantities, finishing requirements and production schedule. Include your target delivery date.
常见问题解答
Can you quote a design that is still in development?
是的. Send the current CAD model and available drawings, and identify any undecided materials, dimensions or finishes. The quotation will state the relevant assumptions. Design changes may require a revised quotation.
Can you review thin walls, deep pockets and connector openings?
Submit the CAD model and dimensioned drawing with the required wall thicknesses, pocket depths, corner radii and opening locations. These features are reviewed for machining access, workholding and inspection feasibility. Any proposed geometry changes require your approval.
How should I specify grounding and thermal contact surfaces?
Mark the areas on the drawing and define flatness, surface finish, masking and coating exclusions. State whether acceptance applies before or after finishing, and include any applicable specifications. Product-level electrical or thermal validation requirements should be identified separately.
Can I request a dimensional inspection report?
是的. Include the dimensions to be reported, the required format and any sampling or first-article requirements. The inspection and documentation scope is confirmed during quotation.
