DON'T JUST TAKE OUR WORD WATCH TO SEE HOW IT WORKS
Engineered for Maximum Performance
Advanced valve technology delivering superior process control and consistent quality for injection molding operations.
Precise Shutoff Control
Mechanically operated poppet valve provides instantaneous and precise closure at sealing surface, ensuring shot-to-shot consistency and eliminating material waste through superior shutoff performance.
Independent Operation
Valve operates independently of screw movement, facilitating valve shut-off at melt recovery and eliminating the need for decompression while maintaining optimal process control throughout the molding cycle.
Patented Technology
Features patented Mini-Shut™ technology with replaceable shutoff cartridge (Patent #8734146), providing proven reliability and cost-effective maintenance for extended operational life and consistent performance.
Durable Construction
Standard construction utilizes wear-resistant heat-treated H13 tool steel with optional metallurgical and surface treatments available for extreme abrasion and corrosion environments, ensuring long-term durability.
Enhanced Productivity
Reduces scrap rates and reject rates while improving overall part quality, maximizing yield rates and increasing profit margins through consistent part-to-part weight control and superior process repeatability.
Versatile Applications
Compatible with most resins processed in injection molding including standard thermoplastics, LSR processing, structural foam molding, and difficult-to-process resins with customized design options available.
Frequently Asked Questions
What size range and materials are compatible with this valve?
The Posi-Shut™ valve is available in 50MM and up for thermoplastics, with customized design and size ranges available for Liquid Silicone Rubber (LSR) processing. It's compatible with most resins processed in injection molding, including standard thermoplastics and difficult-to-process resins.
How does the valve achieve such precise shutoff performance?
The valve uses Belleville springs to create kinetic energy that expedites valve closure, achieving instantaneous and precise closure at the sealing surface with each shot. This mechanical system ensures repeatable performance and consistent part-to-part weight control.
Can the valve be customized for specific machine configurations?
Yes, owner Mike Durina will design a custom Posi-Shut™ Automatic Shut-Off Valve to fit your specific machine make and model. Technical staff is available for consultation on design considerations, especially for molding applications involving difficult-to-process resins.
What construction materials and treatment options are available?
Standard construction uses wear-resistant heat-treated H13 tool steel. Metallurgical and surface treatment options are available for extreme abrasion and corrosion wear environments, ensuring optimal performance in demanding processing conditions.
