Model LP Mandrel Puller

The Blockwise Model LP is a fully pneumatic tool for removing mandrels from catheters after swaging.

Model LP is fast, reliable, and designed to protect both the catheter and the mandrel. Its intuitive design allows an operator to set up and remove mandrels in seconds, making it an efficient addition to any production line.

Engineered for speed and safety, the LP Mandrel Puller streamlines mandrel removal while reducing downtime and risk of damage. Its adjustable design fits most products without size-specific tooling, making it a versatile and reliable choice for catheter manufacturing.

Key Features & Benefits

Short Process Time: Remove mandrels in less than 5 seconds with automatic return to the starting position.
Product Protection: Each gripper’s pressure is independently controlled to maintain a firm hold while safeguarding your product.
Quick Adjustments: Fixed grippers can be repositioned up to 43 cm at the push of a button, with optional extendable components for even greater versatility.
High Strength: Pull mandrels with up to 110 N without risk to your product.
Safe & Intuitive Operation: Fixed grippers resist movement up to 195 N, and the moving gripper operates smoothly with a simple press of a button.
Compact & Clean Room Ready: At 71 cm wide by 23 cm deep, with optional 61 cm extension, the LP fits easily into tight spaces and is suitable for clean room environments.

Quick Setup – The fixed grippers hold the catheter and markerbands in place. The moving gripper pulls the mandrel out. Alignment and setup take just a few seconds.

Universal tooling – Polyurethane grippers securely hold a wide range of products while keeping fingers safe from any pinch-points.

Simple Controls – Just press a button to reposition the fixed grippers. Adjust the gripper actuation pressure with the turn of a knob.

Check pressure with pressure verification ports on back of machine. One-way valves make it easy to check by just plugging in a tube connected to a pressure gauge.

The LP requires no maintenance – just keep the machine clean. You may clean the machine by blowing with compressed air or wiping with 99% isopropyl alcohol and lint-free swab or cloth.
