Mastics Extrusion Equipment

When you demand a mastics extruder that can handle highly viscous materials where rigid tolerances and high temperatures are required, Diamond America’s customized design/build approach ensures the maximum output of the highest quality.

Our engineered solutions ensure maximum durability when handling materials ranging from butyl, silicone rubbers, caulking materials, tape adhesives, epoxies and other demanding materials.

Mastics Extrusion Equipment Features:

  • Large feed openings combine optimum capability with minimal space requirement
  • Extensive jacketing and screw porting for precise temperature control throughout the process
  • Dual drives offer maximum process flexibility
  • Units can be supplied with Auto-Loader and tote bins sized for any batch.
  • Designed to handle bales of tenacious materials with trouble free operation.
  • Optional bearing support eliminates the possibility of screw to barrel contact, even when cold feeding.
  • Customized dies provide for even flow, consistent form, and ease of use

Twin Feed Extruders

Twin Feed Extruders
Application: Catalyst, Food, Mastics

Diamond America’s Twin Feed Extruders feature our counter-rotating feed screw design. It provides our customers with the ability to process the most challenging materials while maintaining a positive feed to the extrusion screw. Our completely original design changes the geometry of the screws, barrel liners and feeders used in the extrusion process. As a result, we are able to reduce unwanted friction and eliminate stagnation while operating at peak energy efficiency. 

Built to handle the hard stuff — Petrochemical Catalysts, DeNox Catalysts, Carbon, Rubber (EPDM and Recyclable), Silicone, Clay, and Ceramics — as well as Food Manufacturing (Confectionary, Pet Food, Pasta).

Twin Feed Extruders are available in 2”, 4” or 6” base models, and can be customized to include various die assemblies (profile or pellet processing), temperature control options, and rotary or guillotine cutters.

Bulk Feed Extruders

Application: Mastics, Forming

Diamond America’s Bulk Feed Extruders are designed and built to handle large batch material straight from the mixer to eliminate the cost of handling. Dual drives offer maximum process flexibility.

The standard large capacity feeder and temperature controls make this an ideal extruder for processing mastics and butyl sealants. As with all Diamond America equipment, our Bulk Feed Extruders can be customized to meet your specific needs.

With proven results in several markets, from catalyst, mastics and ceramics to food, plastics and consumer products, Diamond America manufactures extrusion equipment designed to work and built to last.

Not every application, processing condition and end product is created the same. Our first step in the development a customer’s extruder is thorough research. This includes testing your materials in our lab to determine the ideal extrusion process for producing the high quality structured products our customers demand.
