Precision Plastic Screw Machining Solutions

Plastic fasteners are no less important than metal fasteners nowadays as the former is being used for multiple industrial applications. With similar dimensional thread class and suitable standards, threaded plastic fasteners include screws, bolts, studs, rods and nuts. The non-threaded varieties include Rivets, grommets, pin fasteners, retaining rings, inserts, clips, spacers, clamps, harnesses, wire bundlers, ties and quick-operating fasteners.

The plastic screw machining process plays a vital role when it comes to acquiring precision-made nylon screws of high quality and durability. For years, Sun Pattern Plastic Inc. has been successfully delivering plastic screw machining services in Illinois. We offer high performance plastic screws with unmatched accuracy and efficiency with the help of CNC screw machining methods.

What is Acrylic and why is it popular?

The clear-glass like plastic that we often see in stores, showroom and malls, and point-of-purchase displays is Acrylic. In chemical language, it is known as poly methyl methacrylate (PMMA) and commercially, it is called the acrylic glass. Certain preferable features and properties of acrylic have made it a better alternative than glass to produce different types of items.

Following are some of the most popular advantages of using acrylic instead of glass:

  • Acrylic is a transparent thermoplastic, which is popular for being a lightweight, shatter-resistant, and durable.
  • Acrylic is also an economical alternative to glass when the items made out of them are not required to be heavy or strong.
  • The light weight of acrylic makes it an easily conveyable material.
  • The optical clarity of acrylic enhances its aesthetic appearance.
  • It can also be fabricated to meet tight tolerance requirements.
  • It can be given a gamut of coatings, such as frosted finish, screen printed finish, laser cut finish, and many others.
  • The appearance of acrylic can be highly accentuated with the use of LED lighting, which makes it versatile in terms of usage options.
