Graco Fluid Automation 633
Air-powered, proportional control for two-component liquid silicone rubber (LSR)
The double-acting plungers of Model 633, driven by a common cylinder, ensure that material is delivered consistently at a 1:1 ratio. Its larger shot size capacity and ability to feed material to multiple locations make Model 633 an excellent solution for high-productivity medical, consumable and electronics manufacturing environments.
Programmable feed pressure makes it possible to utilize a common tandem feed station for one or more locations. Use the third stream option simultaneously feed different mixes.
A reduced number of components and fewer valves than most designs lowers the cost of cleaning and maintenance.
Consistent refills, less waste
The pneumatic proportional air-driven cylinders keep material refilling at a consistent rate.
With ratio tied to the A and B transducers, and an audible and visible refill alarm, the possibility of drawing a vacuum and wasting material is very low.
A quick refill time of only three seconds at 3000 psi pump pressure keeps manufacturing running at a quick pace.
Wider variability in mold sizes
With a maximum shot size of 150 cc, Model 633 is capable of handling a wide range of manufacturing jobs.
Hoses, mixer and manifold are standard.
