Why Choose Us: Your Small Batch CNC Machining Experts

When you need low-volume manufacturing services, you might share the concerns of our customers: Will delivery be fast enough? Will it cost reasonably? And can the final part meet your exacting precision standards?

At Protofirster, we offer a professional solution for these challenges. Even with MOQ 1, we can do the same comprehensive, professional services. Before the parts production, our experienced team will provide DFM (Design for Manufacturability) support, designing from the ground up to ensure feasibility and cost-effectiveness.

Cooperation with the machining capabilities of our 3 production shop facilities and the rigorous assurance of ISO 9001 certification, this means that every part you produce will not only be guaranteed high precision, perfectly meeting your design requirements, but also enjoy one-on-one production services and industry-leading, quick-turning delivery times, helping you quickly enter the product testing phase.

Strong Manufacturing Capabilities & Industries

Meeting your customized needs is our top priority, so we maintain the flexibility of our production line. Manufacturing capabilities play unique roles at different stages of product development, supporting the entire chain from prototypes to mass production. Scenarios and Values in the Product Development:

1. Rapid Prototyping / Functional Prototypes:

• Application: Rapidly produce 1 piece or small quantities of prototypes using materials like aluminum, stainless steel, and engineered plastics in the early stages of design.
• Value: Quickly validate design, functionality, assembly, and user experience; accelerate design iterations, shortening time to market; and reduce the risk of errors discovered during the mold development phase.

2. Small Batch Production / Bridge Production:

• Application: Produce hundreds to thousands of units during mold development for full-scale production (such as injection molding) or during market testing or initial sales.
• Value: Allows market validation without high mold costs; meets early market demand; and serves as a transitional solution between prototyping and mass production.

3. Custom Parts / Tooling & Fixtures:

• Application: Manufacture high-precision, one-off, or very low-volume custom parts for specialized equipment, automation equipment, or special applications, or produce custom molds and fixtures for after processing.
• Value: Meet special needs, ensure the precision and performance of specialized equipment, and improve production line efficiency and product quality.

4. High Complexity / Critical Parts Manufacturing:

• Application: Manufacture key components in aerospace, medical devices, robotics, and other fields that require extremely high precision, surface finish, and material properties.
• Value: Ensure parts meet the most stringent industry standards and performance requirements, ensuring product safety and reliability.

Multi-faceted Surface Finish

Finish Services is a secondary process for improving a part's surface function, including appearance, corrosion resistance, wear resistance, and electrical conductivity. It includes: anodizing, sandblasting (bead blasting), brushing, polishing, electroplating, passivation, painting (powder coating), heat treatment, laser marking, and chemical plating.

While there are many options, not all are suitable for all materials. For example, anodizing is good for used aluminum alloys, while passivation is used for stainless steel.

The choice depends on the part's application, material, design requirements, cost, and specific appearance and performance requirements. Compatibility issues may exist between different surface treatments, so selection requires a case-by-case approach.

What materials are used in Precision CNC Parts？

Selecting the processing material is a key step to the success of the project. There is no absolute "best" material, only the material that best suits the specific application requirements.
