Our Machining Capabilities
CNC Milling and Turning
DSR uses advanced CNC machines to cut plastic blocks or bars into the desired parts. Whether simple shapes or complex geometries, CNC machining ensures high precision and consistency, ensuring every part fits perfectly.
Four-Axis and Five-Axis Machining Centers
For parts with complex structures and varying angles, DSR is equipped with advanced four- and five-axis machining centers. This allows for single-step molding, reducing setups and assembly errors, resulting in more precise parts and faster implementation of your designs.
Drilling, Milling, and Turning Processes
Different parts require different machining methods. We select the appropriate process based on design requirements, from removing excess material to machining intricate details, saving time and reducing waste.
Surface Treatment
We understand that parts must meet dimensional requirements and perform reliably in real-world use. Through surface finish on machined plastic parts, DSR achieves high precision, smooth, burr-free surfaces, allowing parts to enter assembly directly, eliminating subsequent rework and additional processing.
Plastic Materials We Work With
The choice of material is usually what saves or ruins a part from actually doing what it is intended to. Not only do we work with a vast range of engineering plastics, but we also provide experienced material selection recommendations according to your application so your product is effective as well as cost-efficient.
ABS: Durable, light, and affordable, it’s commonly used for prototypes and enclosures.
POM (Delrin): Abrasion-resistant and lubricating, it’s ideal for moving components and gears.
Nylon: Tough and impact-resistant, it’s widely employed in mechanical parts.
PEEK: High temperature and high strength, it’s predominantly employed in high-performance sectors such as aviation, medical, and automotive.
PTFE: Because of its extremely low coefficient of friction and extremely good resistance to chemicals, it’s optimally suited for seals and chemical equipment.
Wherever you need a cost-effective solution or a high-performance material, we can determine the right material and re-engineer it into a completed part to your specifications through precision machining.
What Our Clients Say
“We used DSR’s CNC machined plastic parts on our automated equipment. The tolerances and accuracy were superb, and assembly was very slick. They are the best machined plastic parts company that we’ve ever had the pleasure of working with. The plastic is so light and corrosion-proof, and overall performance was better than expected.”
“DSR is a good machined plastic component supplier. Their engineers helped us in the optimal selection of plastic material and redesigning for maximum functionality. They further machined the small shapes of the components with excellent accuracy. They met deadlines, and after-sales service was okay. I am greatly satisfied with their product.”
“We purchased DSR’s plastic pump, valve, and pipe fittings for application in our water treatment facility. Their machined plastic surface finish is excellent, and the parts have been stable and dependable in service with no leaks or wear issues. They are lighter and faster to install than the metal parts we were using. I strongly recommend them.”
Our high-performance engineering plastics (such as POM, PA, PEEK, PTFE) are precision CNC machined or molded into our plastic components. Depending on the material and design, the components can sustain tens to hundreds of kilogram levels of pressure or tension under industrial conditions with high toughness and wear resistance. If extra strength is required, our engineers can also specifically design the component to provide stable and reliable performance.
Both plastic and metal parts have their own advantages and are suitable for different applications. Plastic parts are low in weight, resistant to corrosion, and resistant to chemicals and liquids, rendering them ideal where there is low force or where chemicals and liquids are being exposed. They are machinable into complex contours and precise accuracy and meet rigorous demands on both functionality and aesthetics.
Metal parts are tougher and more suitable for applications subjected to high forces, high temperatures, or high pressures in service. If your application requires high mechanical forces or tough operating conditions, metal parts are generally a better choice.
Your final material choice must consider your own application environment, loading conditions, and budget constraint. If uncertain, please have our engineers called in.
Machined plastic part pricing depends on material, size, complexity, technology of the process, and quantity of the order. It is best that you forward us with your CAD drawings or designs so we can evaluate and provide you with an accurate quotation right away. Whether you require small-batch customization or large-volume production, we offer competitive price machined plastic parts with prompt delivery.
