One of the premier pet collar and leash manufacturers in North America was unable to find a supplier who could weld to his pull test requirements 100%. The company wanted welded D-rings with very specific pull test requirements ranging from 900 lbs to 1500 lbs with a near 0% failure rate.

The imported product they were receiving was very inconsistent, with pull test failure rates approaching 20% on some lots. By nature, the pull test deforms the product and, in fact, exceeds the tensile strength of the wire.

Philip machine re-designed our welding machines with specialized cooling units to ensure consistently strong welds and allow for very high production rates, resulting in an exceptionally strong and economical welded D-ring. We added SPC pull testing during the entire production process and satisfied all the customer's requirements.
