Benefits of ProMace

REPEATABILITY AND ACCURACY - Our aim when designing ProMace was to significantly improve upon the repeatability and accuracy of the mace snag testers available in the market.

James Heal ProMace - suspended mace ball holders for mace snag testing

SUSPENDED MACE BALL HOLDERS - The mace balls are stored in non-contact mace ball holders, which in contrast to other instruments, are designed to remove the risk of pin damage.

James Heal ProMace cylinder length reduces threat of damage to the pins

REDUCED THREAT OF PIN DAMAGE - The unique design of the cylinder length on the James Heal ProMace offers a significant reduction in the threat of the pin points breaking.

VDA COMPLIANT - When used in combination with IMAT-UVE mace balls the James Heal ProMace is compliant with the standard of the VDA, Verband der Automobilindustrie e. V., the German Automotive Industry Association.

James Heal ProMace has a 2 x 2 roller configuration, saving bench space

2 x 2 ROLLER CONFIGURATION - The vertical 2 x 2 configuration of our Mace Snag Tester has a smaller footprint in comparison with other instruments of this type, offering a saving of over 50% of your valuable laboratory bench space.

REMOVABLE CYLINDERS - Our sample holder cylinders are removable, which makes the fitting and drying of the felt sleeves and the mounting of samples extremely easy. This further improves the efficiency of the testing process.

Touchscreen User Interface

Our designers worked closely with users and our textile technologists in our working laboratory to produce an intuitive touchscreen user interface that makes ProMace easy to control. All aspects of the test can be controlled in a simple and intuitive way.

The ease of use will reduce training times as it can be used by all levels of Operator. The familiar feel of our touchscreen is similar to devices used every day, users become an expert instantly.

Designed for Safety and Efficiency

When we were designing ProMace the safety of the person performing the testing was of paramount importance. This is why the ProMace is enclosed within a safety guard. It is also the reason our designers created a mace ball inspection holder.

This was specifically designed for the user to hold the very sharp mace ball safely and securely and allows the pins to be changed easily and without pin damage or injury to the user - as illustrated below. Additionally the unique collar design of the mace ball inspection holder enables the user to rest the mace ball on a surface without damaging the points or work surface.

1. Remove the top coupling from the ball chain and attach the ball and chain to the spring clip.

2. Carefully place the mace ball in the cup and gently pull the spring down into the bottom connector.

3. The mace ball is now safe and secure in the holder ready for inspection of the points.

Removal Debris Tray

REMOVABLE DEBRIS TRAY - ProMace is fitted with two sliding removable trays to collect the debris from the test. These can be easily removed for cleaning.

SAFETY GUARD - A hinged interlocked safety guard fully encloses the instrument to enable the testing to be performed with complete safety.

INSPECTION OF POINTS - With the mace ball held in the inspection holder, the examination of the points takes place using the magnifying glass supplied.

What type of fabric would you test on ProMace?

HEAVYWEIGHT FABRIC - Mace snag testing is a test method used to test heavyweight fabrics and apparel such as military uniforms.

AUTOMOTIVE SEAT FABRICS - ProMace is designed to perform mace snag tests on automotive seat covers including seating used in railway carriages.

UPHOLSTERY & FURNISHINGS - Our Mace Snag Tester is used to test robust fabric such as domestic and commercial upholstery and home furnishings.
