chamfer
Used to remove sharp edges, improve assembly and feel; more friendly to appearance and safety.
Polyvinyl Chloride (PVC)
Polyvinyl Chloride (PVC)(Polyvinyl Chloride) is an engineering plastic with excellent flame retardancy and chemical corrosion resistance, and can be adapted into hard or soft materials according to the formulation.
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
Used to improve surface details and appearance consistency; it can be graded in accordance with appearance standards.
bonding
Suitable for separate assembly, extended parts or scenes with limited structure; it is recommended to note the bonding surface and strength/sealing objectives.
screen printing
Suitable for logos, scales and logos; it is recommended to provide vector files and position and size instructions to facilitate alignment and batch consistency.
Laser engraving
For use with serial numbers, QR codes and permanent identification; it is recommended to specify contrast targets and acceptable surface texture variations.
Why Choose PVC (Injection Molding)
cost friendly
Suitable for low-cost general parts and large-scale production needs, it is easier to strike a balance between budget and delivery.
Corrosion resistant
Suitable for parts exposed to common media and humid environments (please note the specific media and temperature to facilitate material/formula evaluation).
electrical insulation
It can be used for insulating structural parts and protective parts; if there are any withstand voltage/creepage distance/certification requirements, please indicate them in the drawings or remarks.
Finishing covers common needs
Supports chamfering, grinding, bonding, screen printing, and laser engraving, adapting to appearance marking and assembly delivery scenarios.
Recommended Applications
- low cost common parts: Cost-sensitive parts such as structural parts, shells, supports, etc.
- Corrosion resistance requirements: Functional parts in humid environments or in contact with common media
- Electrical insulation requirements: Insulating brackets, protective parts, isolation parts, etc.
- Need identification: Screen printing/laser engraving for logo, scale, serial number
It is not recommended to use it directly (it is recommended to change materials/processes)
- Higher strength/wear resistance: It is recommended to evaluate more matching solutions such as PA / POM / PC / PBT
- Higher temperature resistance: It is recommended to evaluate heat-resistant engineering plastics or switch to other process routes
- High appearance and texture: If you need higher surface and color difference control, it is recommended to note the appearance standards and evaluate the material/texture/mold plan.
- Complex thin-walled + strict tolerances: It is necessary to evaluate the risk of shrinkage and deformation based on the structure and mold plan.
Design and DFM Guidelines
- Wall thickness consistency: Try to keep the wall thickness uniform and avoid sudden changes in thickness; in thick areas, it is recommended to use ribs instead of "solid thickening" to reduce the risk of sink marks and deformation.
- Release and draft angle: It is recommended to reserve a reasonable draft slope on the appearance surface/texture surface to reduce strain and top white; when there is texture, the slope requirement is higher.
- Fillets and stresses: Add fillet transitions to the internal and external corners to reduce stress concentration; this is especially important near assembly holes and buckles.
- Gate/ejector mark control: If you are sensitive to appearance, please define the appearance surface in the remarks; we can cooperate to evaluate the gate location and ejection pin avoidance strategy.
- Bonding and assembly: If bonding is required, it is recommended to reserve the bonding overlap surface, positioning structure and assembly gap, and state the strength/sealing/appearance goals.
