Plastics are rapidly growing in popularity as they offer a wide range of functionalities and are available in various aesthetic designs and shapes. Plastics are incorporated into the production of several constructive parts. This brings to the aspects of welding and machining in the production of plastics. To begin with, we will discuss plastic welding.
What You Should Know About Plastic Welding
Plastic welding involves the process of co-joining softened surfaces of semi-finished plastic surfaces with the use of heat; except with solvent welding. There are three stages that are involved in the welding of thermoplastics; they include surface separation, application of heat and pressure, and cooling. There are several welding methods that are created to join semi-finished plastic materials. These welding techniques include hot gas welding, speed tip welding, contact welding, extrusion welding, hot plate welding, induction welding, high-frequency welding, non-contact/IR welding, injection welding, laser welding, ultrasonic welding, friction welding, and spin welding.
To successfully test plastic welds, certain conditions must be met by the inspector and the test method as well. Furthermore, testing quality is divided into two different types: destructive and non-destructive testing. With destructive welding, the central focus is on qualifying and quantifying the weld joints. On the other hand, non-destructive welding is done to discover discontinuities, anomalies, cracks and/or crevices. For destructive testing, the part that is tested will be destroyed, whereas non-destructive testing still allows you to use the tested part afterwards.
What You Should Know About Plastic Machining
Due to the evergrowing demand for plastic and it’s various purposes it serves, this material would have to undergo machining at its manufacturing phase. Plastic has the tendency to hold up for a long period of time while maintaining its aesthetic. Not too long ago, material options were limited in availability. However, this has changed over time, as there is an endless list of materials that are used to produce different functional parts. Each day, new plastics are introduced into the market. As a result of the physical and chemical properties of plastic, it is easy to use these items in construction and other applications. Here is a list of some of the plastic materials that are used in machining:
Acrylonitrile Butadiene Styrene, also known as ABS, a popularly known plastic that is used in the manufacturing of LEGO toys. Due to its high impact strength and toughness, it serves a well-rounded option in the manufacturing world. It is easy to machine this type of plastic and provide an optimum finish – polish, paint, glue, and the rest. ABS guarantees durability as it is sturdy and resistant to heat.
Acrylic, also known as Plexiglass, is an inexpensive alternative for applications that incorporate the use of see-through components. It is scratch-resistant and can be glued easily. However, it is not as strong as other plastics and may crack or break if excessive force is applied.
High-density polyethylene, popularly known as HDPE, is a thermoplastic which has a high strength-to-weight ratio. This product is highly resistant to chemical activities and provides electrical insulation, which makes it good for wiring projects. It is highly durable and has the capacity to withstand weather elements. HDPE is great for outdoor applications and cost-effective.
