Chamfering (improves assembly and safety)
Used to remove sharp edges and improve assembly introduction and feel; it is recommended to unify chamfering standards for exterior parts and handheld parts.
Nylon 6 (PA6)
Nylon 6 (PA6) is a commonly used engineering plastic with advantages such as "good toughness, wear resistance, and cost-effectiveness," making it suitable for lightweight functional parts, sliding parts, and assembly structures.
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.
Key Material and Manufacturing Parameters
Engineering note: Values below are typical reference ranges. Final manufacturability, tolerances, material condition, surface finish, cost, and lead time depend on the drawing, geometry, quantity, and selected process.
Upload CAD files and mark critical features for an engineering review before production.
| Process | CNC machining (plastic machining) |
|---|---|
| Material | Nylon-PA6 (engineering plastic; balanced strength/toughness, good wear resistance, suitable for lightweight parts) |
| Machining tolerance | ±0.2 mm (common range; it is recommended to mark tolerances on key mating surfaces and confirm them separately) |
| Minimum wall thickness | ≥0.8 mm (recommended value; deformation and clamping solutions need to be evaluated for thin walls/large flat surfaces) |
| Service temperature | About 120℃ (related to working conditions, load and environment; please note the usage conditions if there is a sustained thermal environment) |
| Tensile strength | 45–55 MPa |
| Density | About 1.02 g/cm³ (lightweight and friendly) |
| Appearance and surface | It can be polished to improve the feel and knife pattern; it can be spray-painted to unify the texture; it can be silk-screened/laser-engraved to achieve logos. |
| Assembly method | Supports bonding assembly; hole position/thread/mating surface can be re-finished as required (2D marking is recommended) |
| Finishing | Chamfering, grinding, bonding, screen printing, laser engraving, painting |
| Typical lead time | Relevant to size, quantity, structural complexity and finishing; clear delivery and expedited options will be given after uploading the file |
Finishing
Polishing (improving surface texture)
It is used to reduce knife marks and processing marks, and improve the consistency of touch and appearance; the appearance surface can improve the polishing level.
Bonding (part assembly/complex structure)
Suitable for assembly after sub-part processing; it is recommended to reserve a positioning structure and sufficient bonding area during the design stage, and describe the use environment in the remarks.
Screen printing (logo and pattern)
Suitable for logos, scales and graphic information; it is recommended to provide vector files and position and size descriptions, and define appearance surfaces.
Laser engraving (durable marking)
Suitable for serial numbers, QR codes and wear-resistant marks; if there are requirements for color contrast, you can confirm the style first.
Spray paint (unify color and texture)
It can produce matte/high-gloss and other effects, significantly improving the "finished product feel"; it is recommended to provide reference pictures and color number/texture targets.
Why Choose Nylon-PA6 (CNC Machining)
Balanced strength and toughness
Suitable for functional validation and small batch delivery of structural parts and assemblies, providing a better balance between "durability/cost".
Lightweight has obvious advantages
Density is lower than metal, suitable for weight reduction and handheld parts; more friendly to moving parts, brackets and shell parts.
Good wear resistance and sliding properties
Suitable for guides, sliders, bushings, wear-resistant gaskets, etc.; the service life can be further optimized through structural and surface solutions.
Appearance and logo can be customized
Supports polishing and painting to enhance appearance; screen printing/laser engraving facilitates the implementation of brand and traceability logos.
Recommended Applications
- Lightweight structural parts: Want to lose weight but still need certain carrying capacity and toughness
- Assembly/Functional Verification: Need an assembly and use experience that is closer to real working conditions
- Wear/sliding parts: Guide, sliding contact, light load wear-resistant parts
- Appearance upgrade available: Polishing/painting/screen printing/laser engraving to meet logo and texture needs
It is not recommended to use it directly (it is recommended to change materials/processes)
- High temperature and long-term stability: For continuous high temperature/thermal aging conditions, it is recommended to evaluate more heat-resistant engineering plastics or metals
- Ultra-high precision fit: The requirements for micron-level fit/form and position are extremely high and require individual evaluation and consideration of more stable materials and process routes.
- Strongly corrosive chemical environment: It is recommended to choose a more chemical-resistant material system according to the medium.
- Limit size sensitive to water absorption: Changes in ambient humidity may affect dimensions, requiring material and structural countermeasures
Design and DFM Guidelines
- Moisture content and dimensional stability: PA6 will absorb moisture and may cause slight dimensional changes; it is recommended to mark tolerances on key mating surfaces and indicate the use environment (indoor/moisture/water vapor).
- Thin wall and deformation control: Thin walls, large flat surfaces, and long cantilevers are more likely to be deformed under the action of clamping and processing heat; it is recommended to reinforce/thicken, reduce ultra-thin large surfaces, and reserve finishing allowance.
- Fillet and tool accessibility: Internal right angles usually cannot be processed into "sharp corners". It is recommended to add an corner radius to the internal corner (which is better for strength and processing cost).
- Holes/Threads and Assembly: It is recommended to provide 2D markings for key holes; if plastic threads need to be repeatedly disassembled and assembled, inserts or optimized thread structures can be considered, and the number of assembly times and torque requirements should be stated in the remarks.
- Appearance surface definition: If you need painting/screen printing/laser engraving, please define the appearance surface, logo position and texture target; the appearance surface can be prioritized for finer polishing standards.
