Q1.Are you trading company or manufacturer?
A:OBT was established in 2003,specializing in the production of casting, CNC machining, forged titanium alloys, high temperature alloys, brass products and one-stop technical solutions for more than 20 years.
Q2. Do you customize products according to our design drawings ?
A:Yes, we are a professional metal manufacturing factory with an experienced engineering team that can make customized products according to customer drawings. We can also reverse-engineer drawings based on samples to produce large quantities of goods.
Q3.Will my design drawings be safe when you get it ?
A:Yes, we will not publish your design to a third party unless your permission is obtained. We can sign NDA before you send the drawings.

Q4:How to avoid mass order quality problems?

A:Strengthen prior prevention and inspection of the production and processing process, regard important processes as the focus of quality control, and track inspection and defense throughout the process. It can provide Spectrometer,CMM, Tensile testing machine, Impact tester,Hardness tester,X-Ray,Salt spray test box, Pneumatic detection,UV accelerated weathering tester,dynamic balancing, high-temperature tensile testing,fluorescence test,room temperature mechanical property testing and other testing.
Q5.What's your delivery time?
A:In general,the delivery time is within 15-90 days after payment.

Q6.Bolt placement and bolt spacing requirements?

A: The bolt arrangement can be divided into parallel and staggered arrangements. The parallel bolt arrangement is simple, neat and compact, and the size of the connecting plate used is small, but the cross-section of the component is greatly weakened; the staggered bolt arrangement is not compact, the size of the connecting plate used is large, and the cross-section of the component is weakened. Less stress.
