T0, T1, and T2 samples will be prepared as per customer’s actual requirements.

We will assist our customers to get their parts as requested with the closest cooperation.

Step 3: Production and quality control

After the final design approval, we will start to arrange production plan according to delivery schedule, including raw material sourcing, machine tool commissioning, machining, quality control, surface finishing, etc.

All parts are closely inspected at least three times, such as FAI, PQC & IPQC, FQC.

We take full responsibility to make sure your parts meet your expectations.

Step 4: Packaging and Warehousing

Testimonials

What They Are Saying

When it comes to precision machining, my standards are very high. Before I partnered with Sindparts, I was switching suppliers every three months, for they were unable to reliably deliver quality. However, Sindparts set the standard for reliability, cooperation, communication, superb quality parts. It's been two years now, and Sindparts is still my #1.

We are a designing company in the USA. We started to work with Sindparts about two years ago. They are one of our good on-demand plastic injection molding suppliers in China, their price is competitive, yet the quality and service is quite good. They make me feel safe & easy for our business and I am very happy to have them be our key partner.

I am a supply chain manager from a German company, I often need to purchase a lot of CNC machined parts and die casting parts. I tried several manufacturing partners but was not happy. Then I found Sindparts. They provide expert insight from prototype to production, and really help me a lot with our design work and save our money.

We run a machinery business in Malaysia. Most of our precision CNC machining parts are machined by Sindparts, they provided the professional and cost-effective solutions for our project, for example, 4-axis machining parts, aluminum parts, ABS prototypes, and more. We are very satisfied and will keep close long-term cooperation with them in the future.
