CNC Machined Plastic Parts from Shenzhen Ruiyihang Technology give you the accuracy, speed, and engineering know-how your project needs. We've been in business since 2008 and make unique plastic parts with tolerances of as little as ±0.02 mm. Because our method is based on engineering, you talk directly to experienced engineers—no middlemen—who look over your plans, make designs better, and offer useful solutions. We've been in the manufacturing business for more than 9 years, and our engineers have worked in the field for an average of 15 years. We can help with projects from the prototype stage to mass production, and we can give samples in as little as 3 days for simpler shapes.
You deserve a better source than most people. During the whole job, our team gives you direct technical help. We look over your plans and tell you how to make the material choice, structure design, and finishing of the surface better. This joint method cuts down on mistakes and speeds up the lead time by a lot.
We work with high-performance products that are specifically made for your needs:
All of the materials meet the standards for foreign certification, and there is full documentation provided.
There are multi-axis CNC cutting centers with 3-axis, 4-axis and 5-axis tools in our building. This lets us work with small details and complex forms that can't be cut without this. After the main process, steps like deburring, cleaning, and special surface treatments make sure the parts are just right.

Quality isn't just a promise—it's our standard practice. Every project follows strict inspection protocols:
We provide measurement reports, material certificates, and process documentation for CNC Machined Plastic Parts upon request. For projects requiring food-contact safety, we ensure FDA compliance.

Speed is important. Quick quotes after reviewing the drawings, quick prototypes, and flexible production schedules keep your project moving forward.
Full Openness: During processing, we can send you photos and videos so you can see exactly how your parts are being made.
We make everything to order; we don't sell stock items. Each part is made exactly according to your plans and instructions (OEM/ODM).
How to Solve Problems: Are you having trouble with a difficult sewing task? Our team loves taking on tough projects and coming up with new ways to solve problems.
Dependable After-Sales Support: If you report a problem with the quality within the same month, it will be fixed within a week, and the shipping costs will be paid in full.

Q: Which plastics can be CNC machined?
We machine engineer POM, Nylon, PTFE, PEI (ULTEM), PC, ABS, PPS, and others for specific applications.
Q: Why choose plastic parts for CNC machining?
Plastics are lightweight, corrosion-resistant, electrically insulating, and appropriate for chemical or mechanical applications.
Q: Which plastic pieces are better for CNC or injection moulding?
Prototypes, low-volume runs, and thick pieces benefit from CNC machining. Small to medium complicated pieces are better mass produced with injection moulding.
Q: Can you make my design more fabricatable?
Absolutely. Our engineers evaluate every drawing and offer real solutions to boost machining productivity, save costs, and increase part performance.
Q: What about international shipping?
Our door-to-door delivery is optimised for small-batch orders. For simplicity, duties and shipping can be combined.
