The use of multi-gating makes it much easier to fill and pack out the part in an injection mold.

With multiple gates, we are effectively reducing the flow length by positioning the gates in strategic locations to have plastic reach the end of fill in a shorter path. By placing more gates on a part, opportunity presents itself to reduce the wall thickness more than it would be possible with a single gate, while reducing the part weight by as much as 15%.

Most often when using multiple gates on large parts, however in some cases this technology is also used in smaller parts, in this case on the cup shown below 👇 , the part can be made thinner due to the second gate and at the same time enables a consistent flow pattern in a multi-compartment cup like this, since the 2 compartments are filling at the same time.

StackTeck provides development services for PET Preform molds ranging from 2 to 144 cavities. Standard and customized mold frames & pitch layouts are available to accommodate a variety of leading platforms and preform applications.

Medical Molds experience at StackTeck is focused on offering solutions for medical-disposable items, research, testing and diagnosis plastic components and medical packaging. In many cases these components are very intricate requiring complex mold ejection sequences and/or designs, as well as quality optical finishes.

StackTeck’s technology portfolio can create the right Medical Mold solution using one of many of the applicable technologies: stack molds, multi-material, collapsing core, unscrewing and slide action.

Light-weighting of plastic parts has become a special priority for both brand owners and processors in the packaging industry. Light-weighting offers plastic material reduction, reduces the carbon footprint of the package, as well as the overall cost of the package. It also reduces waste downstream (less material per package) as an added bonus.

Thin Recess Injection Molding (TRIM™) is one of the many innovative technologies developed by StackTeck that uses an advanced engineering approach of reducing portions of wall sections for a given plastic part, well beyond the conventional approach for thinwall packaging. TRIM™ parts are engineered using the latest in computer aided design, MFA and FEA, to optimize melt flow through varied ultra-thin wall sections while maintaining target part strength.

Quick Product Change is based on 2 major components; QPC

mold frame and QPC core and cavity module sets. The QPC mold frame incorporates the hot runner power, water and air services, part ejection actuation and mold alignment features.

The QPC core and cavity module sets are specific to a given product and are changed out in sets to enable rapid product change over.

👇 This 24 cavity (3X8) QPC Stack mold produces 150mm round lids at 5.5 second cycles, or 16,000 parts per hour. If demand is greater, this 3 level mold can be extended to a 4 level mold minimizing initial capital and part costs to customers.

StackTeck also incorporates our QPC approach in our in mold label systems to enable rapid product and label changes in 45 minutes.

If you are in looking for injection molding solutions for living hinge cap applications using recycled polypropylene resin, we have the solution!

Have a look at the latest press release issued by PureCycle Technologies! 👇

Living hinge caps are one of the toughest tests for recycled polypropylene.

They need to flex hundreds of times without failure … Traditionally, virgin PP has been the standard. Until now!

PureCycle and StackTeck have now successfully produced living hinge caps using up to 100% PureFive® recycled polypropylene resin, with lids passing hundreds of flex cycles without failure.

This is big news for brands in food, beverage, personal care, and household products seeking recycled-content solutions without compromising packaging performance.

When material innovation and mold expertise come together, recycled polypropylene is no longer waiting for the future. It is proving itself in the applications brands rely on every day.
