Free Design for Manufacturability (DFM) Analysis

Before machining begins, our engineering team reviews your fixture design. This free DFM analysis identifies potential issues, suggests improvements, and optimizes your design for efficient production—wall thickness optimization, feature accessibility, tolerance refinement, and material selection guidance.

What is the best plastic material for jigs and fixtures?

The best material depends on your specific application. For general-purpose precision fixtures, Delrin (POM) offers excellent dimensional stability and machinability. For electrical applications, G10 or FR4 provides superior insulation. For high-temperature applications, PEEK or Durostone may be necessary. Our material specialists help you select the optimal material based on operating conditions and budget.

What is the difference between G10 and FR4?

Both G10 and FR4 are fiberglass epoxy laminates with similar mechanical and electrical properties. The key difference is flame retardancy: FR4 contains flame-retardant additives making it self-extinguishing (UL 94 V-0 rated), while standard G10 does not. Choose FR4 when fire safety is required (PCB test fixtures, electronic testing). Choose G10 when maximum mechanical strength is the priority.

Why use plastic fixtures instead of metal?

Plastic fixtures offer several advantages: they won't scratch or damage delicate parts (non-marring), they weigh 40-80% less than metal (lightweight), they provide excellent electrical insulation, they resist corrosion and chemicals, and they often cost less to manufacture. Choose plastic when surface protection, weight reduction, electrical insulation, or corrosion resistance are important.

What materials are suitable for wave solder pallets?

Wave solder pallets require materials withstanding high temperatures (280-380°C) and aggressive flux chemicals. Durostone and Ricocel are industry-standard materials offering excellent thermal stability, chemical resistance, and machinability. High-temperature FR4/FR5 variants can serve lower-temperature applications. These materials should also provide ESD-safe properties (10⁶ to 10⁹ ohms surface resistivity).

What tolerances can you achieve on plastic fixtures?

Our standard CNC machining tolerance is ±0.03mm (±0.0012"). For critical features, we achieve tighter tolerances down to ±0.01mm with appropriate material selection and machining techniques. Note that different plastics have different dimensional stability—materials like G10 and Delrin hold tight tolerances more easily than flexible materials like UHMW-PE or PTFE.

Do you have minimum order quantities?

No minimum order quantity (NO MOQ). We manufacture single prototype fixtures through high-volume production runs. This flexibility allows you to test fixture designs before committing to large quantities, and order exactly what you need without overbuying. One piece or 10,000—we deliver the same precision quality.

How quickly can you deliver custom fixtures?

Typical lead time for custom plastic fixtures is 5-10 working days after order confirmation, depending on complexity and material availability. Simple fixtures using in-stock materials can ship within 3-5 days. Expedited manufacturing options available for urgent requirements. We ship globally to USA, Europe, Australia, and worldwide.

Can you machine complex 3D fixture shapes?

Yes! Our 5-axis CNC machining centers handle complex 3D geometries including undercuts, compound angles, and organic shapes. We machine virtually any fixture design that can be defined in CAD. For extremely complex designs, our free DFM review ensures manufacturability and optimizes for efficient production.
