introduction
Plastics in CNC Machining
CNC machined plastics are versatile for various applications, from prototypes to end-use components.
Despite being challenging to machine, their lightweight and simple geometries make them often preferable to 3D printing or injection molding. These materials vary in durability and machinability, with options like ABS for cost-effective design testing. With 180+ expert employees, DEK is confident in providing high quality CNC machined precision plastic parts. CNC machining of plastics involves using computer-controlled machines to shape plastic materials accurately. We have the latest and most advanced CNC machining equipment designed for plastics.
For best results, DEK can help you choose the right plastic for your project, considering properties like strength and transparency. DEK uses carbide end mills for cutting and optimizes machine settings, adjusting spindle speed and feed rates to prevent issues like overheating. We use proper coolants or lubricants to help maintain optimal temperatures during machining. We plan efficient toolpaths, secure the plastic material with fixtures like clamps, and ensure effective dust collection. We do regular quality checks and adjustments, and post-processing steps like polishing may be needed. We are committed to providing 100% customer service satisfaction.

TECHNOLOGY OVERVIEW
Basic Knowledge of CNC Machining Plastics
What is Plastic?
Plastic is a polymer, a large molecule composed of repeating structural units called monomers. It can be classified into two main types: thermoplastics and thermosetting plastics. Thermoplastics can be melted and reshaped multiple times without undergoing significant chemical change. While thermosetting plastics harden irreversibly when heated, making them suitable for durable applications.
Plastics are created through polymerization, a process where monomers join together to form long chains or networks. Additives like plasticizers, stabilizers, and colorants are often incorporated to enhance properties or appearance. DEK has different types of plastics available, such as nylon, acetal, polyethylene, polypropylene, and many more.
