polish
Used to remove parting lines, small burrs and surface defects to improve assembly feel and appearance consistency.
Nylon (PA)
Nylon (PA) effect resin is often used in vacuum casting for structural validation parts with "better toughness and stronger impact resistance," suitable for functional samples requiring snaps, drop resistance, or some elasticity.
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.

Finishing
spray paint
Used to unify color and texture (such as matte/high gloss). It is recommended to provide reference drawings and clarify the appearance and acceptance criteria.
screen printing
Suitable for logos, scales and other graphic information; it is recommended to provide vector files and location and size instructions.
Laser engraving
Suitable for serial numbers, logos and durable text; it is recommended to describe the visual requirements of light and dark effect targets and positions.
Why choose nylon-PA (vacuum casting)
Structural validation better matches
For structural validation needs, it is suitable for functional prototypes and assembly evaluations (material selection and process routes can be further optimized based on working conditions).
Lightweight orientation
Material positioning includes lightweight requirements, which is suitable for weight-sensitive prototype and verification parts solutions.
Parameter balancing facilitates "cost-performance" balance
As a common option for vacuum casting, it is suitable for you to balance cost, appearance and performance and iterate quickly.
Secondary process friendly
Supports polishing, painting, screen printing and laser engraving, making it easy to present the appearance and implement the logo information.
Recommended Applications
- Structural validation: Used for structural scheme comparison, assembly interference inspection and functional validation
- Lightweight orientation: Weight-sensitive prototypes and verification parts
- Small batch verification: A replica route that requires multiple pieces for testing/display/review
- identification information required: Screen printing/laser engraving for logo, scale, serial number, etc.
It is not recommended to use it directly (it is recommended to change materials/processes)
- Long term high load use: If the parts require long-term load-bearing and durable use, it is recommended to evaluate more suitable engineering materials and mass production processes.
- Requires extreme precision/ultra-thin extreme structure: It is recommended to conduct a DFM review or evaluate other process routes first
- Certification/brand parameters need to be clarified: Please note the requirements and confirm the material system and verification plan with the engineer
- Mass production: Vacuum casting is more suitable for small batches. For mass production, it is recommended to evaluate injection molding and other processes.
Design and DFM Guidelines
- Key dimensions and assembly surfaces: Please mark the key hole positions/datum plane/assembly relationships in 2D drawings or notes to facilitate the formulation of gate and parting strategies and avoid risks in advance.
- Minimum wall thickness control: It is recommended that the wall thickness should not be lower than the minimum wall thickness requirement (0.8mm) given on the page; the thin-walled area should be kept as uniform as possible to avoid sudden changes in thickness.
- Appearance surface definition: If you need to spray paint or are sensitive to appearance, please define the appearance surface and acceptable defect standards to reduce rework and delivery fluctuations.
- Preparation of identification information: It is recommended to provide vector files for screen printing; for laser engraving, it is recommended to reserve a flat area and clarify the depth and visual requirements.
- Instructions for use assist in selection: Please note the purpose of "structural validation/functional validation/appearance display/assembly trial assembly", etc., so that we can give more suitable material and process suggestions.
