Our Procedures for Manufacturing Dowel Pin by Lathe Machine:

1.The customer provide a sample or drawing(in stp, step, igs, pdf or cad format) to us, these information must be very clear ie. Material , Surface treatment, Tolerance, Order quantity,special requirement, packaging requirement etc.
2.After our sales translated some notes on the drawing into Chinese, our engineer will evaluate the production cost for the part. If there are any questions or problems on the drawing, we will communicate with the client at once by email or by Whatsapp. We will audit the price and send quotation to the client ASAP. 
3.Negotiate with the client about the order and confirm the payment terms, delivery time
and shipping cost. We always try our best to provide best service to our clients, if they need a shipping agent, we will recommend a reliable and trustworthy one for them to make sure deliver the goods timely and costly.  
4.During production, our sales will update the status weekly by email.
5.Once finish production, we will inform you to pay the balance, then arrange the shipment for you. 
6.After the client receive the products, please give us feedback about our product quality. If the parts were damaged or ruined during shipment, we would arrange new one to replace of bad parts for our clients.

Q&A:

1.Q: What is CNC machining process? 
A: CNC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders. The CNC in CNC Machining stands for Computer Numerical Control. On the surface, it may look like a normal PC controls the machines, but the computer's unique software and control console are what really sets the system apart for use in CNC machining. Under CNC Machining, machine tools function through numerical control. A computer program is customized for an object and the machines are programmed with CNC machining language (called G-code) that essentially controls all features like feed rate, coordination, location and speeds. With CNC machining, the computer can control exact positioning and velocity. CNC machining is used in manufacturing both metal and plastic parts. 

2. Q: What is Passivation? 
A:The passivate process is designed to remove foreign metals and oils (usually from machining) from the surface of stainless steel. The end finish will not change the dimension of the part nor the overall appearance of the base metal. Passivation purifies the surface of a machined part and therefore improves corrosion resistance.
