Raw materials and control

                                                                                                                                        

Jinchuan Nickel, Niobium Bar, Molybdenum Metal, Baosteel Industrial Pure Iron Only use the best quality Jinchuan nickel and Baosteel industrial pure iron, with a nickel purity of up to 99.99% and industrial pure iron purity of up to 99.8%, to control the impurity content of materials from the source

Process Control

                                                                                                                                        

The entire process control is carried out from raw materials, material melting, forging, wire drawing, spring winding, finished product inspection and warehousing, and after-sales quality tracking and resolution. Quality control runs through the entire process of product design, material synthesis, spring forming, and overall operation.

Dual process --VIM+ESR:
·VIM is a method of melting furnace materials by using electromagnetic induction to generate eddy currents in metal conductors under vacuum conditions
·ESR is a method of melting using the resistance heat generated by the current passing through the slag as a heat source.
·The dual process used by OBT can control the chemical composition of the Invar smelting process to the greatest extent possible. Through processes such as electromagnetic stirring under vacuum environment, high-temperature smelting, chemical refining, and condensation crystallization, high purity, extremely low impurities, dense and uniform metallographic structure and chemical composition of the Invar alloy are produced, which has excellent physical and chemical properties.
Quality Control:
During the material melting process, OBT conducts five quality inspections, including two vacuum melting and three electroslag remelting. Strict process monitoring is carried out on the samples obtained from smelting using a spectrometer and chemical detection to ensure that the chemical composition and metallographic structure of the final steel ingot meet the highest quality requirements of the Invir alloy in the United States.

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.
