CNC Plastic Machining Materials
We provide complete solutions for any projects with the production of plastic parts machining, below are typical of the materials in our process:
ABS is a plastic material with three main ingredients: acrylonitrile, butadiene, and styrene. Each of these monomers imparts specific properties, making ABS terpolymer with robust features. ABS has good strength, toughness, and resistance to impact and temperature. It is easily molded and gives a high-quality glossy surface finish. This plastic polymer does not have a specific melting point.
LEADRP offers a complete ABS machining service and can produce custom ABS parts in various shapes and grades.
Nylon plastic (PA) is a synthetic thermoplastic polymer commonly used in injection molding applications. It’s a versatile, durable, flexible material often used as a more affordable alternative to silk, rubber, and latex.
LEADRP offers a complete Nylon machining service and can produce custom Nylon parts in a variety of shapes and grades.
Polycarbonate(PC) is a thermoplastic polymer containing carbonate groups in their chemical structures. Polycarbonate has good stiffness and thermal resistance due to its molecular structure and reasonably high viscosity. Polycarbonates can be molded and thermoformed with great ease, making them a popular choice for a wide range of products.
LEADRP offers a complete polycarbonate machining service and can produce custom polycarbonate parts in a variety of shapes and grades.
Polyethylene (PE) is generally divided into multiple groups based on density. These include low-density polyethylene (or LDPE), medium density polyethylene (MDPE), high-density polyethylene (HDPE), and ultra-high molecular weight polyethylene (UHMWPE or UHMW). The higher the density, the higher the tensile and flexural strength, chemical and abrasion resistance, and surface hardness.
LEADRP offers a complete Polyethylene machining service and can produce custom Polyethylene parts in a variety of shapes and grades.
PET(Polyethylene Terephthalate) or polyester is a semi-crystalline resin with a good balance of strength, stiffness, toughness, a natural high gloss finish, excellent chemical resistance, and good dielectric properties. PET is approved as safe for contact with foods and beverages worldwide; PET is sustainable, completely recyclable, and they are the most recycled plastic. PET is commonly used in Plastic components in electrical products, Electrical encapsulation or insulation, Electrical insulation polymers, Connectors for electrical, Packaging or containers for consumables and food, and Appliances.
LEADRP offers a complete PET injection molding service and can produce custom PET parts in various shapes and grades.
Acrylic(PMMA) is a glass-like plastic, their excellent weatherability, good resistance to fading caused by UV and fluorescent lighting, and high resistance to scratching, durability, and natural transparency mak it a good material choice for food storage containers, refrigerator drawers,automotive and consumer products. Acrylics are also well-suited to overmolding and other specialized injection molding processes.
LEADRP offers a complete Acrylic injection molding service and can produce custom Acrylic parts in various shapes and grades.
Polyoxymethylene (POM), also known as Delrin® or Acetal, is a thermoplastic engineered material used to make parts that require increased stiffness, low friction versatility, and more excellent dimensional stability. POM has high tensile strength, wear resistance, creep and warp resistance, and overall toughness and durability. POM is widely used in manufacturing gears, bearings, conveyor parts, automotive parts, sporting equipment, electrical components, sliding and guiding parts, and so on.
LEADRP offer a complete POM/Delrin®/Acetal injection molding service and can produce custom POM parts in various shapes and grades. LEADRP will work with you to produce injection molded Delrin® parts that meet the exact specifications of your project.
Polypropylene (PP) is a polyolefin or saturated polymer, like polyethylene (PE) and polybutene (PB). PP is one of the most versatile polymers with good chemical resistance, fatigue resistance, better temperature resistance, and lower density than HDPE.
PP is widely made for buckets, bowls, crates, toys, medical components, washing machine drums, battery cases, and bottle caps. PP can be elastomer modified for bumpers and talc-filled for added stiffness at high temperatures.
LEADRP has been producing injection-molded polypropylene parts for over 10 years. Our team has extensive experience and expertise in delivering molded PP parts in even the most complex shapes. We can help you decide which of these plastic materials is best suited to your specific application.
Polytetrafluoroethylene (PTFE), also known as Teflon®, is a synthetic tetrafluoroethylene with numerous applications. PTFE has high thermal stability, good chemical resistance, and high-temperature resistance.
PTFE products also have excellent sliding properties, electrical resistance, and a nonstick surface. PTFE can be reinforced with glass fiber, carbon, or bronze additives to improve mechanical properties. Due to its structure, PTFE is frequently formed into semi-finished products using compression molding and then machined with cutting/machining tools.
PEEK is a family of high-performance thermoplastics. The name PEEK is derived from the words polyether ether ketone.
PEEK is a engineering plastic used for a wide range of applications where it needs to be strong and tough. It has good chemical resistance and can withstand high temperatures up to 260°C.
PEEK has excellent mechanical properties, making it suitable for applications such as medical implants, automotive components, and even aeronautical parts. PEEK is also used in electronic components such as connectors and insulators.
Like High-Performance Plastics, Engineering Plastics, Industrial Plastics, Biocompatible Materials, Food Safe Plastics, and Other Modified Thermoplastics. There are many other plastic or resin materials for different applications. Whether it’s on our material list or not, we could source them from a certified supplier for your project.
CNC Machined Plastic Parts
Overview of CNC Machining
The CNC machining process, use computerized controls to operate and manipulate machine tools that cut and shape stock material. Furthermore, the process follows the same basic production stages as all CNC machining processes, which include:
- Creating a CAD model
- Creating a CNC program from the CAD model
- Configuring the CNC machine
- Carrying out the machining operation
The CNC machining process starts with the design of a 2D or 3D CAD part. The completed design is then exported to a CNC-compatible file format and converted by CAM software into a CNC machine program, which instructings the machine’s actions and tooling movements across the workpiece. Before running the CNC program, the operator must first prepare the CNC machine by attaching the workpiece to the machine’s work surface (worktable) or work holding device (e.g., vise) and attaching the milling or turning tools to the machine. Depending on the specifications and requirements of the machining process, the CNC machine will use different cutting tools such as mills and drills. When the machine is ready, the operator starts the program via the machine interface, instructing the machine to perform the machining operations.
Benefits of CNC Machining
CNC machining centers are quick and precise, allowing for the efficient production of complex and specialized products. CNC machining has lots of advantages, including:
Cost Savings
Every business seeks ways to reduce costs while maintaining quality. CNC Machining enables the efficient production of complex and specialized products because they work faster and more accurately.
Safety
When a CNC machine is running, there is no bending or crouching required to operate the machines. So, there should be fewer workplace accidents and less fatigue, which reduces the risk of human error in the machining process significantly. And also, the safety and ergonomic conditions for workers are greatly improved.
Efficiency
CNC machines can operate continuously with little downtime. A fully-automated CNC machining facility can keep running without interruption 24 hours a day, seven days a week.
Versatility
One of the most significant advantages of CNC machining is its versatility. CNC machining enables manufacturers to cut or shape a wide range of materials while maintaining quality and efficiency.
CNC milling are ideal for a wide range of complex, high-quality production runs of all sizes. CNC machines will also save you a lot of time and money because of their operational efficiency and lower labor costs.
