CG.Tec has recently introduced a laser source on an injection-molding line.
The project dates back to the late 2000’s, when CG.Tec identified substantial cost savings for the customer.
Francis Pichot, automation manager, explains the concept:
“Once injected the parts are unloaded through a gripping hand. As their orientation is known, introducing an additional operation does not require extra effort. The cycle time remains unchanged: the part is marked while another one is being injected.
If considered as individual steps, parts undergoing further operations need to be orientated through vibratory bowls, which always represent significant investments and is time demanding. Integrating extra processes on a production line is therefore not only cost effective but also reduces the lead time.
This concept attracts more and more customers, who identify CG.Tec not only for the know-how in tool-making and injection-molding, but also in process integration.
Miniature, precise and technical is CG.Tec’s motto. Following this leitmotiv a third Micron d’Or (Golden Micron) was granted to CG.Tec on Micronora exhibition for a lab-on-a-chip presenting 7 micron details out of injection.
To successfully achieve this result CG.Tec entered in partnership with several universities, research centers and companies.
With this major technological progress CG.Tec proved that injection-molding is a serious alternative to hot-embossing. Produced at a high throughput parts are cost effective. A chance for the development of microfluidics.
By the end of 2013, CG.TEC acquired a new Arburg injection machine dedicated to micro-injection.
This new generation machine presents several advantages:
First of all: an optimal performance. The shot volume is reduced thanks to the smaller screw of 8mm (previously: 12mm). As a matter of fact, this creates a competitive advantage for expensive materials such as PEEK.
Using a smaller screw also improves the part reproducibility as the dwell time of the melt is shortened during plasticizing.
This new piece of equipment perfectly fits with our core business: miniature injected parts.
