Development Background
New Customer & Initial Setup
This is a new customer, marking the first time we have developed these specific parts. Following a thorough background investigation of both parties, we signed the "Mold Development Agreement", "New Product Trial Production Agreement", and "Supplier Integrity Agreement" before starting development.
Challenging Development Cycle
The development cycle for this product was extremely tight, with the first sample delivery time set to 40 days. Processing presented high difficulty, particularly with a mounting hole tolerance requirement of ±0.012mm.
Leadership & Equipment Investment
From the receipt of the development notice, the project department led the initiative, with personal participation from our company's boss. After multiple rounds of meeting evaluations and on-site verifications, we invested in new processing equipment, successfully meeting all customer requirements on the second sample delivery.
Our Capability: Our company features a strong technical development team with the capability to develop OEM parts in the precision casting field. We provide integrated services from blank casting to machining. Our core philosophy is to pursue excellence and provide customers with efficient, high-quality products and services.
