Rapid Prototyping Services
Yinuomold provides rapid prototyping services for custom plastic and metal parts, helping customers verify product design, structure, assembly fit, material selection, and basic function before moving into tooling or mass production. Depending on the part design and project stage, we can support CNC machined prototypes, 3D printed prototypes, plastic prototype parts, aluminum prototype parts, zinc alloy prototype parts, and trial samples for mold-related projects. Our rapid prototyping process usually starts from drawing or sample review, followed by manufacturability evaluation, material and process suggestion, prototype production, dimensional inspection, surface finishing, and sample delivery for customer approval.
Precision
Depends on the selected process, material, and part structure. CNC machined prototypes can support tighter dimensional control, while 3D printed prototypes are mainly used for structure, appearance, and design verification.
Tolerance
Typical prototype tolerance can range from ±0.05 mm to ±0.20 mm depending on the process, geometry, material, and inspection requirements. Tighter tolerance can be reviewed according to drawings.
Capability Details
Service Overview
Rapid Prototyping for Custom Plastic and Metal Parts
Rapid prototyping helps customers test a design before investing in tooling or mass production. For many custom plastic and metal parts, a prototype can help confirm structure, assembly fit, material selection, surface appearance, and possible manufacturing risks at an early stage.
Yinuomold supports rapid prototyping for OEM buyers, product developers, engineering companies, importers, and brand owners who need sample parts before production.
What We Can Support
Our rapid prototyping services may include CNC machined prototypes, 3D printed prototypes, plastic prototype parts, aluminum prototype parts, zinc alloy prototype parts, and trial samples for mold-related projects.
Depending on the project requirements, we can help customers choose a suitable prototyping method based on part structure, tolerance needs, surface requirements, quantity, and production plan.
Typical Prototype Applications
Rapid prototyping is commonly used for product structure validation, assembly fit testing, appearance and design review, functional sample testing, engineering design improvement, pre-tooling confirmation, small-batch sample production, and new product development projects.
From Prototype to Production
Yinuomold does not only support prototype making. When a prototype is approved, we can continue supporting the project through plastic injection mold making, injection molding, die casting mold making, die casting production, CNC machining, surface finishing, inspection, packaging, and delivery.
This helps customers reduce communication gaps when moving from sample confirmation to stable production.
Information Needed for Quotation
To quote a rapid prototyping project, please send us 2D drawings or 3D files, material requirements, quantity, surface finishing requirements, tolerance or critical dimension requirements, application or assembly information, and photos or samples if drawings are not complete.
Our team will review the project and suggest a suitable prototyping process based on your requirements.

Finishing Options
Surface Treatments
Sanding / Polishing
Improves the surface smoothness of prototype parts for appearance review or assembly testing.
Anodizing
Commonly used for aluminum prototype parts to improve surface appearance and corrosion resistance.
Painting
Used for plastic or metal prototypes when customers need color, appearance, or product display samples.
Powder Coating
Suitable for selected metal prototype parts that require a durable coated surface.
Basic Assembly
Simple assembly support can be provided when prototypes need to be checked as a functional unit.
Inspection Before Shipment
Quality Control
Controlled Process, Clear Inspection Points
Key inspection items are organized into visible checkpoints so overseas buyers can quickly understand how the service is controlled before delivery.
QC Checklist
01
Drawing Review
Check drawings, 3D files, critical dimensions, material requirements, and manufacturing feasibility before production.
02
Material Confirmation
Confirm suitable material based on prototype purpose, such as appearance review, assembly test, or functional validation.
03
Dimensional Inspection
Inspect key dimensions according to customer drawings or agreed inspection points.
04
Appearance Check
Check surface condition, visible defects, edge quality, and finishing quality before shipment.
05
Assembly Fit Check
For related parts, check basic fitting, hole position, and assembly condition when required.
06
Final Sample Review
Confirm sample photos, inspection results, packaging, and shipment details before delivery.
