chamfer
Used to remove sharp edges and improve assembly and feel consistency; if there are appearance surfaces and assembly surfaces, please prioritize them in the notes.
Polycarbonate (PC)
Polycarbonate (PC) is a high-performance engineering plastic with extremely high impact strength, excellent transparency, and high heat resistance.
Quote checklist: Upload your 3D model and, when available, a 2D drawing. Identify the required process, material, quantity, critical dimensions, finish, appearance standard, and target delivery date.

Finishing
polish
It is used to improve the surface appearance and remove fine flow marks/edge processing marks; the higher the appearance standard, the more investment in polishing and quality inspection.
bonding
Suitable for component assembly and structural combination; it is recommended to provide assembly direction, bonding surface requirements and assembly tolerances to facilitate stable and consistent implementation.
screen printing
Suitable for logos, scales and logos; it is recommended to provide vector files and location dimensions, and clarify the appearance and acceptable color difference range.
Laser engraving
Suitable for serial numbers, QR codes and wear-resistant logos; please provide content, size and location, and clarify whether slight whitening or surface texture changes are allowed.
Polished (transparent edge)
Used to improve transparent edges or local translucency; please specify the polishing range, appearance surface and assembly benchmark in the drawings/notes to avoid affecting coordination.
Why Choose PC (Injection Molding)
Appearance and performance balance
Suitable for appearance prototype and functional validation projects, making it easier to make a trade-off between budget and delivery efficiency.
Electrical insulation application friendly
It is suitable for structural parts/casing parts that require insulation properties, and can be further evaluated based on the structure and standards.
Logo and appearance processing compatible
Supports screen printing and laser engraving, making it easy to create brand logos, parameter scales and traceability information.
Transparent edges enhance appearance
Optional polishing (transparent edge) improves visual effect; suitable for designs that require partial transparency or edge appearance.
Recommended Applications
- Appearance prototype: Need to quickly obtain a near-finished appearance and assembly experience
- Functional validation: Used for phased verification and iteration of structure and function
- electrical insulation: Shell/structural parts that require insulation properties
- Need identification: Screen printing or laser engraving for logo, scale, number, etc.
It is not recommended to use it directly (it is recommended to make a decision after review)
- Large-area transparent appearance with strong appearance standards: It is recommended to clarify the transparency aspects and standards in the remarks, and do DFM and effect evaluation first.
- Thin wall with large fluctuations in wall thickness: It is recommended to optimize wall thickness uniformity and reduce the risk of shrinkage, warping and filling.
- Deep rib/deep cavity complex structure: It is recommended to first review the demoulding slope, ejection position and filling path.
- Bonded assembly requires high consistency: It is recommended to clarify the assembly process and testing standards, and make samples for verification if necessary.
Design and DFM Guidelines
- Wall thickness uniformity: Try to keep the wall thickness as consistent as possible to avoid sudden changes that increase the risk of shrinkage, dents and warping.
- Draft angle and ejection: For parts with textured/surfaced surfaces, it is recommended to reserve a reasonable draft angle and plan the ejection point in advance to reduce ejection and strain.
- Muscle positioning and strengthening: Using ribs instead of local thickening is more conducive to appearance and dimensional stability; deep ribs need to be evaluated for filling and drafting.
- Bonding and assembly: It is recommended to make a positioning structure (steps/stops/positioning posts) on the bonding surface, and clarify the assembly datum and tolerances in 2D.
- Screen printing/laser engraving area: Reserve a distance between the flat area and the boundary to avoid inconsistencies caused by falling on the parting line, ejection point or strong curved surface.
- Transparent edge polishing: If polishing (transparent edge) is required, please mark the polishing range and appearance surface to avoid polishing affecting the mating dimensions and assembly standards.
