Insta’s Model 158 Digital Auto Release heat press offers one of the major benefits of an automatic machine - the auto-open feature - in the lightweight, lower cost, ergonomic design of a manual clamshell heat press. The Model 158 meets the demands of today’s busy retail environment and is also a practical solution to use as a post-curing agent for the expanding digital direct-to-garment marketplace. Following in the tradition of Insta’s reputation for quality, the Model 158 maintains the ergonomic, compact clamshell style of the Model 138 - and in addition, boasts a time maximizing auto-release feature. After the operator closes the machine, the Model 158 will automatically open once the pre-set time has elapsed. This allows the operator to maximize his/her time while the transfer is dwelling, without having to worry about burning the garment.
