At Miller Plastic Products, our leading-edge Plastic Fabrication Department specializes in fabricating custom plastic heat exchangers matched to your specific needs. Our plastic welding capabilities include Polypropylene, PVC, and exotic high-temperature plastics such as PVDF (Kynar). PTFE (Teflon) is often used for the tubing element within the appliance.
Our welds are second to none, being very smooth and easily cleaned. Nothing leaves our shop with a saw cut edge or a sharp edge. We offer custom CNC routing services- every piece is individually cut out on high-tech CNC routers. Request a quote for our custom plastic machining services today.
