Primer application – Case #555

“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 factory was using a plain nylon brush to apply primer on outsoles. This brush cannot hold the primer due to its low viscosity, what poses a risk of not applying sufficient primer. This may affect the sole bonding.

Impactiva solution: we got the factory to cover the nylon brush with a piece of cotton cloth in order to increase the quantity of primer applied to the outsoles, what will enhance bonding strength.

Material damage – Case #474

“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: foot beds were being stored one on top of the other, the top facing the bottom, what caused the glue on the bottom to stick to the top.

Sole marking – Case #456

“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: over-roughing and over-cementing due to the lack of sole marking in production.

Glue marks – Case #455

“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: glue marks on the uppers, near the straps ends.

case 455 pic 1 impactiva footwear qa

Impactiva solution: we got the factory to use self adhesive tape for temporary attachment of straps in order to avoid using glue on the uppers.

Roughing dust – Case #451

“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 bottom roughing dust was not being removed before glue application, what might cause bonding failure.

case 451 pic 1 impactiva footwear qa case 451 pic 2 impactiva footwear qa

Impactiva solution: we got the factory to deploy an artisan permanently after bottom roughing to clean and remove the dust.

Adhesive application – Case #439

“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 factory was using hot melt adhesive to paste the insocks, but the machine was not set correctly, and a lump of adhesive could be easily felt under the insock, resulting in uncomfortable wearing.

case 439 pic 1 impactiva footwear qa case 439 pic 2 impactiva footwear qa

Impactiva solution: we got the machine set correctly and adhesive sprayed in order to avoid clotting, what improved insocks pasting. We also suggested the factory to change the machine and apply the adhesive on the insocks rather than on the outsoles.

Poor bonding – Case #432

“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 bonding between the footbed wall and the upper.

case 432 pic 1 impactiva footwear qa case 432 pic 2 impactiva footwear qa

Impactiva solution: we got factory to apply primer first, then, a double coat of adhesive on both sides of the footbed , and use a finger pressing machine to improve the bonding of the upper and footbed wall.

Workers protection – Case #416

“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: fumes from PU adhesive may be hazardous for artisans who apply adhesive on shoe bottoms.

case 416 pic 1 impactiva footwear qa

Impactiva solution: we got the factory to provide carbon compound lined masks for the artisans who apply PU adhesive and ensure they wear it regularly.

Wrinkled socks – Case #382

“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: high percentage of wrinkles on the socks in production due to excessive application of neoprene adhesive and lack of drying time (they we pasting the socks to the insoles immediately after applying the adhesive).

case 382 pic 1 impactiva footwear qa case 382 pic 3 impactiva footwear qa case 382 pic 5 impactiva footwear qa

Impactiva solution: we got the factory to apply only one single coat of adhesive on the socks, let them dry for 40-60 seconds, and then paste to the insole. We taught the artisans to avoid glue spots on the lining while pasting and to paste edge to edge.
