Acrylic or Plastic Fabrication in Wisconsin

Different types of plastic fabrication.


plastic fabricationIs it custom products you're looking for?  Or do you need to hire someone with a CNC to cut some material?  Maybe you're looking for someone to do vacuum forming for your company.  Maybe you need a company that can do some line bending for you.  Solvent bonding is another process that plastic fabricators do.  Plastic fabrication comes in various flavors, it's up to you to know which type to source out.

Plastic fabrication and vacuum forming.


Vacuum forming, commonly known by people as  vacuum forming, is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto or into a single-surface mold, and held against the mold by applying vacuum between the mold surface and the sheet.  The vacuum forming process can be used to make most product packaging, speaker casings and even car dashboards.

Plastic fabrication and solvent bonding.


In solvent welding, a solvent is applied which can temporarily dissolve the polymer at room temperature.  When this occurs, the polymer chains are free to move in the liquid and can mingle with other similarly dissolved chains in the other component.  Given sufficient time, the solvent will permeate through the polymer and out into the environment, so that the chains lose their mobility.  This leaves a solid mass of entangled polymer chains which constitutes a solvent weld.

This technique is commonly used for connecting PVC and ABS pipe, as in household plumbing.  The "gluing" together of plastic (polycarbonate, polystyrene or ABS) models is also a solvent welding process.

Dichloromethane (methylene chloride), which is obtainable in paint stripper, can solvent weld polycarbonate and polymethylmethacrylate.  Dichloromethane chemically welds certain plastics; for example, it is used to seal the casing of electric meters.  It is also a component - along with tetrahydrofuran - of the solvent used to weld plumbing.

Plastic fabrication and CNC machining.


Numerical control (NC) refers to the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to manually controlled via handwheels or levers, or mechanically automated via cams alone.  The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape. These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern computer numerical control (CNC) machine tools that have revolutionized the machining processes.

In modern CNC systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a postprocessor, and then loaded into the CNC machines for production.  Since any particular component might require the use of a number of different tools-drills, saws, etc., modern machines often combine multiple tools into a single "cell".  In other cases, a number of different machines are used with an external controller and human or robotic operators that move the component from machine to machine. In either case, the complex series of steps needed to produce any part is highly automated and produces a part that closely matches the original CAD design.
Plastic fabrication

So as you can see there are many types of plastic fabrication.  Be it CNC machining, custom products or simple line bending, it is all readily available.  Solvent bonding can be easily accomplished or some type of vacuum forming is available to your business.  Give us a call hopefully we can help you with your line bending or custom products.  If I can not help I will gladly find a fabricator that will help you with your project.  Plastic fabrication only a phone call away.
