Common Machining Methods – Including Flame Polishing Acrylic & Others

Do you need a plastic component made to your specs? Trustworthy plastic fabrication companies typically serve an array of industry professionals. So, whether you’re involved in electronics, healthcare, instrumentation, or another field, a team of specialists can assist you. Using the latest fabrication techniques and equipment, they’ll attentively create the exact piece you need for your application. Rather than choosing a subpar company, rely on experts who will take special care in designing, machining, and – if necessary – annealing your product.

Techniques Used
Plastic fabrication professionals utilize a selection of different techniques and tools to deliver customized end-products. Many dependable specialists are experienced with completing projects for customers in an assortment of industries. If you’re in need of a polished, clear component, or a tiny piece that requires micro hole drilling, the right company can exceed your requirements. From lathe turning and CNC machining, to plastic milling and micro machining, you can rely on a qualified expert to employ the ideal method to create your unique piece in a timely manner.

Plastic Polishing
Another commonly used method in the plastic fabrication industry is polishing. The process of polishing takes three forms – specifically flame polishing, vapor polishing, and mechanical polishing. Flame polishing acrylic provides a clear finish that’s second to none, while vapor and mechanical polishing are used for internal/external finishing and for components that don’t require high optical quality, respectively. An experienced plastic fabricator will know which method is appropriate for the component you want. Additionally, they’ll know how to complete the process professionally and speedily – ensuring your component is skillfully machined and finished on-schedule.

Importance of Annealing
After a plastic component has been machined and/ or polished, it often needs to be annealed – or heated – to prevent surface damage. Machining, mechanical polishing, vapor polishing, or flame polishing acrylic creates internal stress, which is caused by rapid heating, force, cooling, and shrinkage. These stages leave the fabricated plastic vulnerable to stress cracking and distortions. In many cases, annealing isn’t a requirement. However, after fabrication has taken place, the internal stress of a plastic component sometimes needs to be relieved to avoid problems, particularly if the component is a plastic rod or sheet.
