Sustainability continues to dominate new additives technology, but upping performance is also evident. Most of the new additives have been targeted to commodity resins and particularly polyolefins.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.

The cell also provides flexibility, as it can also be designed with different mounting stands to allow smaller footprints, integrated conveyor systems, or other downstream equipment needed for pre or post moulding automation. The robots can be programmed to work together or can run individually, when one robot can be used when standard two plate moulds are run in the same machine.

When, how, what and why to automate — leading robotics suppliers and forward-thinking moldmakers will share their insights on automating manufacturing at collocated event.

The APSX-PIM machine measures 43 in. long x 12 in. wide x 15 in. high and weighs 250 lb. It was designed for simplicity and low cost. It has no air or water connections. Mold cooling is external, applied by a variable-speed, electronically controlled fan mounted over the clamp. The machine has a feed auger to move pellets from the hopper to the injection barrel, which has a 1-in.-diam. plunger instead of a screw. Heater bands on the barrel provide the energy to melt the small shots of resin. APSX’s in-house molding produces a part in about 60 sec.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

“Customers often call asking for dual vertical arm robots to run stack moulds, but in most cases the high-speed top entry robot cells have proven to be more robust and quicker for those applications,” said Jason Long, national sales manager, robots and automation for WITTMANN. “A lot of moulders who are not stack mould experts do not think of this out of the box until we share it with them, as these type of dual robot cells are unique to WITTMANN.”

While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.

The standard WITTMANN high-speed robots can be mounted to run even the most complex stack mould applications. These cells normally can offer cycle times of 7-12+ seconds, without requiring special robots or causing abnormal wear and tear on dual vertical arm robots, which is the case for robots not designed for quicker cycles.

In this collection of articles, two of the industry’s foremost authorities on screw design — Jim Frankand and Mark Spalding — offer their sage advice on screw design...what works, what doesn’t, and what to look for when things start going wrong.

Plastics Technology’s Tech Days is back! Every Tuesday in October, a series of five online presentations will be given by industry supplier around the following topics:  Injection Molding — New Technologies, Efficiencies Film Extrusion — New Technologies, Efficiencies Upstream/Downstream Operations Injection Molding — Sustainability Extrusion — Compounding Coming out of NPE2024, PT identified a variety of topics, technologies and trends that are driving and shaping the evolution of plastic products manufacturing — from recycling/recyclability and energy optimization to AI-based process control and automation implementation. PT Tech Days is designed to provide a robust, curated, accessible platform through which plastics professionals can explore these trends, have direct access to subject-matter experts and develop strategies for applying solutions in their operations.

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

The four-tiebar clamp is driven by a stepper motor and ballscrew. The injector is driven by a stepper motor pushing against a spring, which pushes against the plunger. A shutoff nozzle opens for injection and closes after mold filling. Max. mold size is 4.8 x 6 in. and clamp stroke is 6 in. The machine costs $12,500, but is available for as little as $6250 to participants in a Kickstarter “crowd-funding” capital-raising campaign started last month. Machines usually ship in two to six weeks; several units were in stock at press time. A video of the machine in action is available here.

The aim of this presentation is to guide you through the factors and the numbers that will help you determine if a robot is a smart investment for your application. Agenda:  Why are you considering automation? What problems are you trying to solve? How and why automation can help Crunch the numbers and determine the ROI

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

WITTMANN USA, a manufacturer of injection moulding machines, robots and auxiliary equipment, has developed a custom robot solution targeting stack mould applications.

Two engineers and entrepreneurs who were buying plastic parts to manufacture a line of automotive aftermarket air/fuel ratio gauges decided they wanted to mold them in-house, but balked at the cost of conventional injection machines. So they decided to design and build their own. About a year ago, Burak Cevik and Kubi Kara, partners in APSX LLC, Blue Ash (Cincinnati), Ohio, came up with a tabletop machine with 7.5-ton clamp and plunger injection unit capable of 1.83 in.3 (3 to 40 g) shot size and 5000 psi injection pressure. All axes on the machine are driven by servo stepper motors—another product line of APSX. The two partners have been using the press to mold cases and bezels of TPO and PP, but they have also used it with HDPE, PS, ABS, and powdered-metal injection molding (PIM/MIM) compounds. Starting in December, the partners began promoting the machine to inventors, custom molders, and small manufacturers of toys and other products for prototype and short-run production.

Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.
