Screws for Injection Molding

Screws, Barrels  for Injection Molding Machines & Extrusion Screws

Heat Tech Systems Inc. and Complete Plastic Systems Inc. have been serving the USA plastics market since 1990! 

We only build the highest quality products, and to OEM spec’s. This means if you buy a screw tip from us, it will match the OEM seats, ring and retainer. Ours will fit the OEM. (This saves you the trouble from ordering after-market parts that only fit their tips and designs). 

Our prices are very competitive, even compared to after-market components. Ours will last much longer, because they are made in the USA. Buy the best! 

The best kind of a supplier will give you certification of all materials, so that you know what the screws and tips are made of. There are so many materials out there, that most customers can’t tell without a test run, what the material really is. (Example: If you order CPM9V from other suppliers, you may be getting D2 Nitride, instead). Inferior parts and materials will not last nearly as long, but the customer doesn’t know until it’s too late. 

Ask for certifications of material. If your supplier will not give it to you, or says they don’t track it, then get a new supplier…call us!

Complete Plastics Systems Inc. and Heat Tech Systems Inc. have been supplying the injection molding industry with screws, for over 25 years. We are highly familiar with the various process issues customers may have in all types of molding, and have helped many customers reduce their cycle times while being able to process with a more consistent process. With even the most corrosive plastics and most stubborn resins, we are able to offer an injection molding screw that can last much longer than what comes from overseas. We can do this by being able to qualify the steel all the way from its stock, through the milling and QC processes, and provide the correct material for your application. 

We have found for high-filled glass applications that a CPM 9V screw works best, and for corrosive materials, your best bet is going with a D2 material that contains chromium for PC, or Delrins type of materials. We work with many types of coatings such as Nitriding, Colmonoy 56, Colmonoy 83, and Carbide Encapsulation.

We also are able to build the injection molding screws to any profile, as well as adjusting the metering, transition and feed sections, to work with almost any type of resin and process. 

As one of the biggest suppliers of screws in the USA, we can rebuild any screws over a 35mm. This can help you save money and get quicker turnaround times on screws. Anything under 35mm is usually too small to weld, without going past the core materials and warping the screw. At that point, a new screw is more cost effective. Rebuilds are a very good option, and will give you the same type of life expectancy.

We stock a large amount of standard size screws for most brands of machines and can build for stocked screws to any custom application. We have built for Cincinnati, Van Dorn, Husky, Nissei, and Toshiba. We have built custom applications where we have downsized a 400 ton Press with an 80mm Screw and barrel package to house a 40mm screw and barrel and cut the shot size down by 75%. 

If rebuilding is an option, we have found that we are able to save the customer roughly 40 to 60 percent of the cost of a new screw. We get sent a lot of repair screws with flight ware or a broken drive end. NOTE: Please don’t throw these screws away! They are great way to have backups for your machines and save cost. 

Let us help you save the screw, and also repair it to its OEM tolerances, and give you a good production screw while saving money.

We supply Mixing Screws and Barrier Designs, for high-wear, in any machine size or manufacturer. We also have certain screws in stock at manufacturing. 

We are experts at production supply! Our staff is made up of maintenance and production people that have many years of molding experience. We listen to your needs and understand what you are looking for. Your needs may vary from a standard OEM Design to a better mixing screw with faster recovery rates. We can work with you on process improvements, or just help you design a standard screw replacement. 

We purchase materials from the best the industry has to offer. We supply only the highest quality USA made components at very competitive prices. We know that the company wants to save money by buying products from China and Mexico, but we find that by supporting the USA manufacturers, and working more efficiently, we are able to supply a better quality product with better support and great prices. We stock a tremendous amount of standard size Screws, Barrels and Tips for most brands of machines and can build anything you need. 

We are able to supply a better quality product, offer excellent support, and give you great prices! Call today to place your order!
