In our daily production work, plastic CNC service is a very common prototype method. But do you really understand the plastic CNC service? Plastic CNC service is a method of rapid prototypes machining, which is convenient to produce prototype to be a mock-up. Now let me unveil its mysterious veil for you.

Definition of Plastic CNC Service

CNC machining of plastic prototype parts is a so-called "subtraction" method because of material removal. In plastic CNC machining (digital computer control), the processing method is to manufacture the plastic parts such as ABS, PMMA, POM, PC, PA, PP, etc. into the parts we need by digital milling machine.

The CNC machine is the main equipment for the production of hand-made plates. The CNC machined samples have the advantages of large size, high strength, good toughness and low cost, and have become the mainstream of hand-made. This is the most efficient and economical technology for quickly manufacturing small batch of prototypes or plastic models.

Status of the Plastic CNC Service

Engineers face with many challenges when dealing with plastic materials such as plastics. Although plastic is a versatile material, it requires precise and efficient processing into useful and low cost shapes. Low conductivity, low density, durability and transparency are some aspects that make plastics adaptable. Few companies provide expertise in engineering capabilities to provide the highest quality machined plastics.

In addition, products made from plastics are low in cost. This is why the demand for plastic processing is high. Plastic processing can also meet the requirements of a few selected industries. Therefore, since plastic is inherently practical and soft. These characteristics also play a vital role in processing.

Of course, the use of flexible materials in plastic processing is not an easy task. Engineers must face with several complex challenges, because a tiny error can result in severe tolerances that can affect plastics that are not shaped to the desired shape, which require a lot of materials to be produced at one time.

Experts use the latest CNC equipment and traditional machines that can process almost all plastic parts. CNC represents computer numerical control and requires the use of programs to control the machining process. Strict tolerances are being required when machining metal, and plastic housings are no exception.

Understandably, the types of machines and technologies used in plastics vary widely because they are much softer than metals. A wide range of customers in almost every industry require professional machined plastics. The preference for plastics, not metals, has increased the demand for expertise in the field of plastics processing.

The use of plastic parts has become so wide-spread that most likely we don’t notice the many items we use that are made completely of plastic or of plastic parts. Many manufacturers have found that by converting their metal parts to plastic ones they can find numerous savings in design changes, overall costs, weight and waste.

Processing Details of Plastic CNC

The machine tool used in CNC plastic machining is a milling machine with 3-axis digital control. They are automatically controlled by the computer to determine the path of the tool based on the 3D file to be created. In plastic CNC machining, no mold is required, thus reducing cost and start-up time. These machines can be designed with several identical copies, so they can get the same quality for all copies of the batch, but with little economies of scale. Wide selection of thermoplastics and metals allows access to components with the required physical properties.

Plastic Provided by Wayken

The variety of characteristics of plastic materials has also increased, including heat tolerance, tensile strength, and chemical resistance. Wayken Plastics, precision machining provides the ability to create nearly any part or component. These are all high-precision, machined plastics, from the simplest to the most intricate with the tightest tolerances for a broad array of standard plastics, as well as many advanced and unusual plastics that other companies won’t handle. Let me now briefly introduce the plastics provided by Wayken.

ABS

ABS is a ternary copolymer of three monomers, acrylonitrile (A), butadiene (B) and styrene (S). ABS is A ternary copolymer of three monomers, acrylonitrile (A), butadiene (B) and styrene (S).

ABS has the common property of three kinds of components. A makes it resistant to chemical corrosion and heat and has a certain surface hardness. B makes it highly elastic and tough. Therefore, ABS plastic is a kind of "tough, hard and rigid" material with easy access to raw materials, good comprehensive performance, low price and wide use. ABS has been widely used in machinery, electrical, textile, automobile, aircraft, ship and other manufacturing industries and chemical industries.

PC

PC is an amorphous polymer in almost transparent glassy state with good optical properties, high strength, good fatigue resistance and weather resistance. The three major application fields of PC engineering plastics are glass assembly industry, automobile industry and electronics and electric appliance industry.

PMMA

PMMA, is also known as acrylic or organic glass, has the advantages of high transparency, low price and easy mechanical processing. It is widely used in automobile industry (signal equipment, instrument panel, etc.), pharmaceutical industry (blood storage container, etc.), industrial application (video disc, light scatter), electronic products' buttons (especially transparent). Consumer goods for daily use (beverage cup, stationery, etc.)

POM

POM, is also known as Acetal, is often used in precision components requiring high stiffness, low friction and excellent dimensional stability. Excellent wear resistance and self - lubrication. POM is often used to make gears.

PA

PA is also called nylon. One of the most commonly used engineering plastics, nylon has excellent abrasion resistance, toughness, high impact resistance and high tensile strength. It is widely used in automobile manufacturing (fuel filter, balance rotary shaft gear), electrical and electronic industry (electric vacuum cleaner, electrical product terminal) and medical apparatus and instruments.

PP

PP is a non-toxic, odorless, tasteless, milky white, highly crystalline polymer, is widely used in translucent plastics in various fields. PP has good fatigue resistance while providing excellent physical, chemical, mechanical, thermal and electrical properties. PP is used in the automotive industry with strong competitiveness, but because of its low modulus and heat resistance, the impact strength is poor, so it cannot be directly used as auto parts.

The modified PP products used in cars are resistant. The heat can be increased from 80 ° C to 145 ° C ~ 150 ° C, and can withstand high temperatures for 750 ~ 1000h without aging, no cracking.

Wayken has a extensive variety of state of CNC machining equipment for customers' complex machining needs and offer conventional plastic machining for the production of high-quality plastic components at competitive prices. This high level of expertise makes it possible for Wayken Plastics to create custom plastic parts and components of the best quality. Wayken stocks most plastic materials and has the ability to do everything from prototyping to production runs.
