Based on the details you have provided, we will prepare a quotation for cost and lead time. On a case-by-case basis, we may also prepare drawings and simulation analyses.
Based on our quotation, you may submit an order for a prototype. Sometimes, we may skip the prototyping phase if both sides are comfortable with our ability to deliver the required items based on prior works.
We will fabricate a prototype and verify it according to the agreed specifications. You can typically expect to receive the prototype within 7–9 weeks after placing the order.
After receiving the prototype, your team will test it in the intended operating environment. If there are no issues, we can provide a quotation for mass production. We accept orders for lots of 100 items or more.
If satisfied with your tests and our quotation, you may place an order for mass production.
