PU vs. Metal Strippers: Why PASS PU Strippers Are the Smart Choice
When it comes to punching metal, the choice of stripper can significantly impact your operation's efficiency and product quality. Opting for a polyurethane (PU) stripper over a traditional flat metal stripper offers several advantages:
Reduced Sheet Marking: PU strippers are softer than metal, minimizing scratches and blemishes on the workpiece, which is crucial for applications requiring a pristine finish.
Noise Reduction: The inherent cushioning properties of polyurethane help dampen vibrations and reduce noise levels during punching operations, contributing to a safer and more comfortable work environment.
Enhanced Safety: Unlike metal strippers, PU strippers do not fragment upon failure, reducing the risk of damage to dies and injury to operators.
Compact Design: PU strippers can exert the same pressure as metal strippers while being smaller in size, allowing for closer center-to-center punch distances and more efficient use of space.
PASS Stanztechnik AG produces a wide range of PU strippers designed specifically for Trumpf-style tooling, ensuring durability and precision. These high-quality PU strippers are available through Zimco Tool, making it easy for you to upgrade your punching process with the best solutions on the market.
Types of PU Strippers Available
At Zimco Tool, we offer several types of PU strippers tailored to different punching applications:
Flat Round Punch Strippers: Ideal for standard punching operations, these strippers provide reliable support and durability.
Round Punch Strippers with Whisper Shear: Designed for punches with a whisper shear feature, these strippers enhance precision and reduce noise.
Forming Punch Strippers: Available for both flat and whisper shear forming punches, these strippers accommodate more complex forming applications.
PU Spring Types: PU strippers come in three different sizes (Type 1, 2, or 3) depending on the size of the punch, ensuring the right fit for various tooling needs.
Blank PU Strippers: This unique option comes without a fully punched hole. Instead, the first punch creates the exact opening needed, making it ideal for applications with extremely tight clearances.
Low-Scratch Stripper: For applications where minimizing sheet marking is critical, PASS offers the "low-scratch-stripper", a metal stripper with a PU coating. This innovative design combines the strength of a metal stripper with the gentle touch of polyurethane, providing durability while significantly reducing the risk of scratches on sensitive materials.
