We do not provide design services. You are responsible for submitting 2D and 3D CAD drawings, and we can then provide a Design for Manufacturing review upon receiving your order.
In order to provide an accurate and timely quote, we only accept 3D CAD files in STL, STEP or IGES format. 2D drawings with reference dimensions must be in PDF format. We must receive complete manufacturing information as part of this technical documentation. Informal communication via SMS, Skype, email, etc., will not be considered as admissible for manufacturing purposes.
In most cases, we respond within a couple of days of receiving an RFQ. If the quote is delayed, we will notify you as soon as possible.
Yes, customer-supplied material is fine so long as it fits with our machine capabilities.
Yes, master models are used to create silicone molds for vacuum casting and can be made from any rigid solid that can withstand heat up to 100° C. Models used for CNC machining will be 3D scanned to create a CAD/CAM program for production.
We of course will sign and adhere to any non-disclosure or confidentiality agreement. We also have a strict policy within our factory that no photographs are ever allowed of a customer’s product without express permission. Ultimately we rely on our reputation of working with hundreds of thousands of unique designs over many years and never allowing any proprietary information to be disclosed to a third party.
Although direct comparisons are difficult, Richconn’s prices will be typically 25-45% less for CNC machined / turned parts when compared to suppliers in North America and Europe.
As compared to Chinese suppliers, we choose to not to compete on price but to offer the highest levels of quality, rapid response and professional results.
Lead times are quoted in calendar days. As per our Terms and Conditions, quoted lead times commence only after completion and confirmation of design for manufacturing review and the beginning of actual production.
Quality parts can be made in as little as two weeks if you provide us with complete 2D and 3D CAD models. More complex parts requiring or other special features will take longer. Request a quote to get more accurate lead times based on your project.
As for shipping, most of our shipments are via air freight, which can take a few days from China to Europe or North America.
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, pointing out any areas where we may not be able to achieve your desired tolerances. 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 time and costs involved.
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.
We offer a wide variety of finishing services to achieve almost any look and feel on your parts. We offer treatments for metal, painting for metal and plastic, and many more.
Passivation is a treatment that changes the surface chemistry of some kinds of metals. We offer passivation for corrosion protection, durability, cosmetics and more.
Yes. We offer a special vapor polishing service to achieve high transparency for your clear plastic parts.
