Advance™ Plunger Rods
Plunger rods are an essential component as a crucial part of the shot end assembly and are responsible for pushing hot metal into the die cavity. Proper design and machining accuracy are critical for plunger rods to ensure trouble-free production.
Two key features of a useful Plunger Rod are cooling and lubrication. Maintaining a tolerable temperature in this hot zone is essential to functionality and the longevity of the rod. The Advance Plunger Rod utilizes a maximum diameter cooling line without sacrificing integral strength. Lubricity between the tip and sleeve are critical and is why we precisely engineered the placement of our plunger lubrication line.
- Manufactured of premium pre-hard 4150
- Engineered for maximum cooling to ensure shot-end longevity
- Built-in lubricity system optimizes production capacity
- Standard wrench flats for easy replacement
- Custom designs and sizes available upon request
- Combine Advance Plungers & Tips with our ‘TLS Series’ Tip Lubrication System
The Advance™ Plunger and Tip Cooling System
Coolant enters and exits the plunger via ¼” npt ports (located in-line as standard). It then flows the length of the plunger rod through a 3/8” diameter brass tube which is supplied extra long and slanted to ensure positive flow to the tip. The Advance™ Plunger Tips have a custom designed coolant chamber that has a unique shape and consistent wall thickness that keeps a consistent temperature to prevent cracks. Our Hi-Temp resistant O-ring seals between the plunger rod and tip inhibits coolant leaks and thermal shocks. Ring-gauged thread tolerances (standard 1 ¼”-12) provides a snug-fit, also.
The Advance™ Plunger and Tip Lubrication System
Utilizing the Advance™ Tip Lubrication system ensures free movement between the shot sleeve and the plunger tip. We locate the lube hole behind the tip and below the centerline, so that the lube is sprayed at the greatest point of contact which is on the bottom. Now your components will freely glide, lasting longer and permit continuous production. Combine our plungers with the Industrial Innovations ‘TLS Series’ tip lubrication system for a complete turn-key operation.
