Any company in manufacturing a product needs to focus on two different aspects of production to make a profit. One is in selecting the lowest cost type of part and component production process, and the other one is selecting the materials to provide a durable part at a low cost.
Plastic makes the ideal material in many industries. It is inert, which means it does not react to liquids or materials carried within the system or those that are on the outside of the system. In addition, plastic is non-corrosive, which makes it ideal for use where long-life cycles for the part and the system are critical factors to consider.
For plastic tubing and parts, there are two common methods of production. One is the use of injection molding, and the other is through custom plastic extrusion. Both offer benefits, but plastic extrusion offers several benefits that are well worth considering.
Fast, Low-Cost Production
Plastic extrusion is a process where melted plastic is forced through a die under a specific pressure. This is similar to squeezing toothpaste out of a tube; it provides a consistent, precise external shape.
The die can be developed to include interior shapes that form different profiles within the inner wall of the tube. It is possible for custom plastic extrusion to create a divider throughout the tube, to have a tube within a tube or to even offer unique shapes for both the exterior and interior surfaces.
The extrusion process is fast, allowing long lengths of the tube profile to be produced through automated systems. With cooling systems in place and the ability to cut the tube to the desired length, this is a fast, cost-effective option.
Variety of Options
The choice of custom plastic extrusion allows for a greater number of different options in the actual plastics used in the part. Companies can produce DEHP-free plastics for the process to provide both rigid and semi-rigid tubing options.
It is also possible to create different surface finishes using the method. These include a glossy, matte or satin type of finish, which often has both a functional as well as an aesthetic requirement.
