733PLC Series Electronic Pattern Sewing Machine for

Extra-thick Material Parts Catalogue

Taizhou Mingyuan Hightex Special Sewing Machine Co., Ltd

Heaviest programmable electric pattern sewing machine for extremely

thick materials and sewing threads

The 733PLC class is one of the most heavy duty programmable electronic pattern sewing machines in

production today. It can be used to stitch many heavy duty applications such as Lifting Slings, Safety

Harnesses, particularly for the Automotive, Aviation and Military Industries.

This heavy duty automatic pattern sewing machines and bar tacking machines will be thoroughly

tested and gone over by our Industrial Sewing Application Center.

Our field engineers configure these sewing automation equipment properly for customer sewing

requirements. This includes building all the necessary clamping, jigging and fixturing to accomplish the

sewing task, testing and checking all pneumatic, electrical, and computer systems for proper operation,

programming the machine with all patterns supplied by the customers, and then testing the machine

on samples that match exact customer specifications.

These operations save the end user many thousands of dollars in extra expense, eliminating the need

for outsourcing the work required to get the machine in operating condition.
