Glue application on straps – Case #650

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: the strap lining gets glue stains because applying the glue on the table stains it and transfers it to the strap.

Impactiva solution: we got the factory to hang the strap above the table during glue application in order to avoid stains on the lining.

The thong strap pulls off – Case #613

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: the thong strap pull-off test fails because the insole board has poor strength.

Impactiva solution: we got the factory to attach a reinforcement tape under the insole board to  improve the tong pull-off strength. We ran new tests and confirmed it now passes (result approx  30 KGF).

Risk of straps pulling off – Case #574

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: the style had very thin straps, so there were high chances of the upper failing the pull off test.

Impactiva solution: we got the factory to stitch a piece of textile at the edges of all the straps in order to provide extra contact area for proper bonding with sole and insole

Poor packing affects quality – Case #567

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: poor packing: the buckles were not wrapped and the straps did not have plastic strips,  so buckles can get scratched and straps can collapse during transit.

X-ray on the outsole – Case #562

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: X-ray on the outsole caused by bulgy strap joints in between the insole and the outsole. The straps ends are open at the grooved area on the insole.

Impactiva solution: we got the factory to install a hot pressing mould machine so that strap ends would be attached at the grooved area on the insole while reducing the bulginess at the straps joint area in between the insole and the outsole.
