Understanding Types of Plastic in Plastic Shops

Plastic shops offer a range of plastic items in a variety of materials. When you are looking for plastic items, the selections can be overwhelming, and you may be uncertain which type of plastic is most appropriate for your needs. Here are some of the most common forms.

 

Acrylic Plastic

Acrylic plastic is a thermoplastic with transparent qualities. Its clear quality gives it a glass like appearance, which makes it an ideal and more durable alternative to glass. The material is frequently used in the automobile industry. For your home, you can easily have acrylics cut and molded for tables and displays as an alternative to glass options.

ABS

ABS is a thermoplastic polymer. It is a lightweight compound, and it can be easily injected into an array of molds. This makes the product extremely versatile in its application. It is commonly used in musical instruments, golf club heads, furniture bumpers and children’s toys. The material is most commonly utilized in a variety of household products. Plastic shops have a variety of molds, and they can help you design a variety of unique items for your home.

PVC

PVC comes in two forms, flexible and rigid. It is one of the most commonly utilized types of plastic and possesses an array of applications. It is used for pipes and electrical cables, and can be used in signs and clothing. At the plastic store, they utilize the material for customized signs.

Which Is Better, Machined Plastic or Mold Injection Plastic?

plastic fabrication

Before embarking on any project involving plastics, you need to ask yourself which method will work best: machined or molded.Injection molding creates a solid piece by putting hot melted plastic into a metal mold, and having it drop out after it cools. Fabricated plastic is made from flat sheets in a similar way to machined metal. The plastic parts are cut out of the sheets and then finished through a multi-stage labor process that can involve drilling, bending, additional cutting and gluing. The main differences in these two methods are as follows:

1.       Plastic Machining

  • Provides precise measurements. This is the preferred method for technical uses in medicine, aerospace, and scientific instruments as parts can be tooled with a high degree of dimensional accuracy.

  • Flexibility in design. You can make a design change in machined plastic at any time, but molds need to be made anew for the injection method, which is costly and takes time.

 2.       Plastic Mold Injection

  • Fast and requires little labor. The mold, once made, can be used hundreds of thousands of times for the same exact result. It finishes well and so does not usually require any additional shaping after it comes out of the mold.

  • Efficient. No waste created from extra material that must be cut away.

Ultimately machined plastic is far cheaper and is the preferred method if you only need a few hundred parts. Injection molding is expensive and only makes sense if you need a high quantity of parts, typically in the thousands, to justify the overhead cost of having molds made.
