“Converters are always looking to enhance their efficiency,” said Eugene Tabone, Rotational Molding Market Manager. “Our new Novapol TRx0338 and TRx0535 grades will help roto-molders leverage the fast sintering properties of these new resins to improve their molding operations.”

A reduction in cycle time enables manufacturers to produce more parts in less time at lower oven temperatures, noted Nova Chemicals, while a broader processing window allows them to run different part sizes and thicknesses on the same arm under identical conditions without sacrificing part quality. Processability characteristics support consolidation of traditional 3.5 and 5.0 melt index or 5.0 and 7.0 melt index grades to a single resin, added the Calgary-based chemicals company.

During the NPE press conference, LS Mtron Global CEO Chai Ho Shin also shared some news about the company’s recent expansions.

There is ample space in the 210,000-square-foot facility on a 10.6-acre lot to manufacture injection molding machines, the company added, which is part of the company’s strategic plan for the United States.

By any measure, LS Mtron Injection Molding Machines USA has been remarkably successful at penetrating the US market in a short amount of time. In 2018, the Korea-based company had 1.5% market share in the North American injection molding machine space. By 2023, that share had grown to 7.5%. And that pales in comparison with the company’s goal of capturing 20% of the North American market. No deadline has been set as yet. It’s a tall order, but consider this, said Paul Caprio, president of sales, at a press conference at NPE2024: LS Mtron has shown consistent growth during fallow times for the plastics industry; imagine what it can achieve under better economic conditions.

With a melt index of 3.5 and a density of 0.938, Novapol TRx0338 resin is suited for molding small tanks, intermediate bulk containers, roll-out waste carts, and material-handling containers for laundry and dry bulk goods. The 5.0 melt index, 0.935 density Novapol TRx 0535 resin is suited for manufacturing toys, recreational vehicle components, kayaks, stand-up paddleboards, and custom parts.

The company is exhibiting in booth W1101 at NPE2024, which is running at the Orange County Convention Center in Orlando, FL, through May 10.

The PE resins from Nova Chemicals reportedly can reduce cycle times by up to 30% and provide a processing window at least 15% broader than traditional hexene roto-molding resins.

LS Mtron is part of South Korean conglomerate LS Group, which employs more than 25,000 employees and has annual revenue in the neighborhood of $30 billion. LS Mtron Injection Molding Machines (LS IMM) is a division of LS Mtron, which was started in 1969 by another South Korean giant, LG Corp. Initially, LS IMM exclusively molded components for LG-branded TVs, appliances, and other products. As LG expanded across the globe, LS IMM followed and since then has installed thousands of machines across North America for automotive, appliance, and other applications. That heritage is valuable, according to Caprio, because it allows LS Mtron IMM to say that “we are molders ourselves. No other machine builder can make that claim,” said Caprio, adding that it gives the company a unique perspective on the best molding machine for a given application and an ability to communicate meaningfully with machine buyers.

In Texas, meanwhile, LS Mtron has established a dual-purpose facility in Palestine, which will serve as a demonstration center and warehouse for its injection molding machine business as well as a second US production facility for the conglomerate’s popular tractors. The company produces more than 12,000 tractors a year at its Battleboro, NC, factory; the new Texas facility will produce another 12,000, doubling the company’s US output.

Two new polyethylene (PE) resins from Nova Chemicals Corp. for rotational molding are designed to accelerate production, lower cost, and improve flexibility. The Novapol TRx0338-U and TRx0535-U hexene co-monomer resins reportedly can reduce cycle times by up to 30% and provide a processing window at least 15% broader than traditional hexene roto-molding resins, said Nova Chemicals. The findings are based on extensive internal and customer testing, said the company.

In South Korea, Shin announced that it is expanding injection molding machine production at a new factory in Jinju. The 15,000-square-meter (3.7 acre) facility cost approximately $12 million and began operations last month. It will produce around 50 presses each month for shipment to customers in the United States, Europe, and Korea.

LS Mtron is reinforcing that message of confidence on the NPE show floor, where it has tripled its footprint to 13,500 square feet and populated the space with several signature production cells. These include a 1400-ton hydraulic press molding an automotive part and a “sandwich” molder that processes virgin resin for the surface layer and recycled materials for the core. The result is a product with a quality appearance and sustainability cred.

Some of the machines are equipped with automation systems, none of which are made by LS Mtron, a point of pride for Caprio. The company prefers to rely on forward-thinking automation experts that pursue innovation, said Caprio, rather than build an in-house team that may develop tunnel vision over time.
