A Hard-Cheese Cutting Blade for Gad Dairies: Food-Approved Nylon 12

We replaced Gad Dairies' brittle aluminum blade with a food-approved Nylon 12 (PA12) blade, strong and resistant to impact and load. The part underwent chemical smoothing that makes it food-safe and resistant to water and chemicals. The result: savings on spare parts, cleaner and safer work, and a fix for a recurring engineering failure.

סכין חיתוך גבינה קשה מניילון 12 (PA12) שהודפסה עבור מחלבות גד, לאחר החלקה כימית

[ 07.12.1 ]

Challenge

At Gad Dairies, the aluminum blade that cut their hard cheeses broke every few weeks. Beyond the cost and downtime, the fractures were a safety and hygiene hazard: a risk of aluminum fragments falling into the cheese. A strong, durable and food-contact-safe solution was needed.

Approach

We identified the engineering failure behind the recurring breakage and designed a new blade from Nylon 12 (PA12): a material especially strong and resistant to impact and load, and approved for food contact. The part went through a chemical smoothing process that seals the surface, adds resistance to water and chemicals, and makes it food-safe.

Outcome

A durable, safe blade replacing the brittle aluminum part: significant savings on spare parts, cleaner and safer work, and a root-cause fix of the engineering failure, for a strong result that lasts.
