Mingrui offers you a wide range of production facilities like extrusion, injection moulding, pressing and casting. Depending on product geometry and quantities, we will choose the suitable technique for your products.For the final finishing of the parts we use CNC machining centres, equipped with diamond tools in order to meet high accuracies.
Our aim is to offer the ideal solution for any application. Our engineers therefore offer custom solutions that range beyond our existing product portfolio. With our well-equipped industrial development facilities, we produce innovations that can be rapidly commercially exploited.

Process of production:
Q1: How to send an inquiry
You can send your drawing with technology requiremens,and infrom
your purchase quantity .If you can,pls inform what is your part
used in .We will confirm what is the most suitable materials and
quote our best price to you in 24 hour
Q2:Can you provide the free samples ?
Yes,we can provide the sample free of charge if we have the stock product as customer's required,but the courier fee be collected.
Q3:How long will it take for you to send me a quote?
This depends on the complexity of your requirements. For simple
items such as plates and rods, we can generally supply a quotation
within 24 hours.
Q4:What's the delivery time?
For the standard products, like ceramic substrate and insulating rods, delivery time is normally 7 working days. For hot pressed boron nitride and machinable glass ceramic, it's about 10 working days. For customized products made of alumina, zirconia, boron carbide and silicon nitride, total producing time is about 30-45 working days.
