There is not a given set of tolerances that fits all processes and materials. In every case, the final tolerances on your part will depend on a number of factors, including but not limited to:
● Part size
● Design geometry
● The number, type and size of features
● Material(s)
● Surface finish
● Manufacturing process
Once your order is confirmed, we will review your design and provide a Design for Manufacturing review, indicating any areas that may require modification in order to improve manufacturability. It' s helpful if you can specify which areas in your design have critical tolerances that must be met and which can be slightly modified if needed to reduce production time and cost. Here are some general tolerance guidelines:
● General tolerances for CNC machining in metal and plastic
● Plastic injection molding tolerances
● Reference charts for CNC metals and plastic injection molding materials
● General tolerance for metal 3D printing is +/- 0.5mm
● Shrinkage rate of +/- 0.15% is to be expected for vacuum casting All manufacturing and technical specifications need to be clearly specified in the 2D drawings in order to be followed.
● Once your order is confirmed, we will perform a full Design for Manufacturing (DFM) review to point out any issues that our engineers feel may affect the quality of your parts.
● All incoming materials are inspected and verified with a suite of testing equipment.
● Final inspection reports before shipment.
● We have the ability to share inspection data with you in real-time so we can work together to address any quality issues you may have during production.
Finishing your order
Our standard terms are Ex Works (EXW) for rapid prototyping and regular production orders. This means the customer is responsible for shipping, customs clearance and all other associated fees once the goods have left our premises.
For express shipments, we use Delivered Duty Unpaid (DDU), which means that the client is responsible for paying import duty when the goods arrive to your destination.
