Our Quality Cookware Production - GPR Cookware

Our Materials




For the production of our pans & pots, only food-grade aluminum is used, which is heat-conductive, lightweight, anti-corrosive and non-reactive to food.




Nonstick coatings from our reliable suppliers are PFOA-free. High wear & temperature resistance ensures both cooking safety & durability.




Made with bakelite which is non-conductive & highly
heat-resistant, handles of our pans and pots will stay cool for easy holding & serving.

Our Process

When it comes to the quality of our cookware, we don't believe in shortcuts.
Every pan and pot will go through at least 8 meticulous processing steps before it becomes GPR Cookware.

Our In-Process Quality Control

  • surface-inspection

    Surface Inspection

    The surface of each aluminum pan or pot is carefully inspected before & after molding to ensure there's no bubble or scratch.

  • dimension-measurement

    Dimension Measurement

    A caliper & dilatometer are used to check if the cookware dimensions, rim thickness & bottom concavity meet the designated requirements.

  • bottom-striking-test

    Bottom Striking Test

    After covering the bottom, our worker will strike the bottom of every pan or pot with a small copper hammer to make sure it adheres firmly.

  • induction-test

    Induction Test

    Then the magnet is used to check the induction performance of every pan and pot by our bottom-covering worker.

  • non-stick-coating-test

    Non-stick Coating Test

    Coating testing machine & 3M 898 adhesive tapes are used to check the thickness, hardness & adhesion of nonstick coating every 1 hour.

  • final-inspection

    Final Inspection

    Every part including the handle & the lid is carefully tested & inspected after assembly. No scratch, grease or unsightly welding spot is allowed.

Our In-house Performance Tests

  • abrasion-resistant-test

    Abrasion-resistant Test

    Anti-abrasion performance of the non-stick coating is tested with 3M 7447 scouring pads which is attached to a testing machine that wipes for 3000 - 5000 cycles.

  • bottom-concavity-test

    Bottom Concavity Test

    Bottom concavity should be within a low value in 10 repeated tests. We measure the value with a dilatometer when the cookware is cooled down from 200℃ to 20℃ after a thermal shock.

  • heat-resistant-test

    Heat-resistant Test

    To test the heat-resistant performance of the non-stick coating, we put the pan or pot into the thermotank and heat to 250℃.

  • salt-spray-test

    Salt Spray Test

    Anti-corrosive performance of the non-stick coating is tested with 5% NaCl. The solution is heated for 7 hours.

  • dishwasher-test

    Dishwasher Test

    We put the pan or pot into the dishwasher for 50 washes (45 minutes each time) to ensure it's dishwasher-safe.
