The growth of horizontal plastic injection molding machines is primarily driven by the increasing demand from key end-use industries such as automotive and packaging. Injection molding has been a well-established manufacturing process for producing plastic, metal, and rubber products across various sectors for many years. This growth is a testament to the dominance of horizontal machines in the plastic injection molding market. As per Astute Analytica, technological advancements have played a crucial role in the growth of horizontal plastic injection molding machines market. Modern machines offer superior precision, speed, and process control compared to older models. Essential elements of molding that were once driven by time and pressure have now evolved to focus on position, peak pressure, and process repeatability. Today, injection molding is considered a highly automated and mature technology, enabling manufacturers to produce ultra-high-quality plastic parts with the highest level of precision and speed.

One of the key advantages of horizontal plastic injection molding machines is their ability to efficiently produce high volumes of parts, making the process highly cost-effective for mass production. Injection molding machines can meet high-volume production requirements once the process is set up, and the high production output rate makes injection molding more cost-effective and efficient compared to other manufacturing methods. Presses can run in size from less than 5 tons to over 4000 tons of clamping pressure, with larger machines capable of producing bigger parts. Larger parts require higher clamping force to keep the mold closed during injection, highlighting the importance of horizontal machines in the production of sizable plastic components.

The main Sumitomo (SHI) Demag stand (Hall B1, Stand 1105) features a fully electric IntElect 180/570-250 injection moulding machine equipped with an LSR package comprising a twin dosing system, robotics, and vacuum and venting peripheral equipment. In a cycle time of just 17 seconds, this IntElect LSR package manufactures 256 individual 0.06-gram single wire seals with absolute precision and stability. Despite this high throughput, the IntElect machine’s energy consumption remains one of the lowest on the market.

To support the high-volume production of individual single wire seals, tooling partner Rico Group reveals its proprietary 256-cavitation LSR mould tool. Combining the direct injection system with double nozzle technology with the IntElect machines optimised clamp force, this LSR package successfully achieves the highest number of cavities in the most compact installation space. The turnkey system coordinates every processing step to efficiently manufacture 256 LSR parts every 15 seconds with minimal flash and material waste. “It’s the definition of high-volume sustainable production,” notes Aliyev.

The electronics and telecommunication sector in Asia-Pacific is also a major contributor to the regional plastic injection molding machines market. The consumer electronics market is expected to reach $450 billion by 2024, with 5G adoption projected to cover 60% of the population. Increased production of smartphones, laptops, and wearable devices, coupled with a 15% growth in China's semiconductor market, underscores the need for plastic components, further boosting the injection molding machines market. Apart from this, healthcare advancements in the region, with a projected market size of $2.5 trillion in 2023, and a telehealth market expected to grow to $50 billion, highlight the increasing demand for medical devices and biotechnology products. These products often require precision plastic components, thereby driving the market for injection molding machines.

The adoption of injection molded components is increasing across various industries, including automotive, electronics, consumer products, and packaging, due to their material compatibility, high precision, and repeatability. Technological advancements are driving the efficiency and effectiveness of plastic injection molding machines, with continuous innovations in materials, manufacturing processes, and digital technologies. The demand for lightweight and intricately designed plastic components in industries such as automotive and electronics is also fueling market growth. As per Astute Analytica, electric plastic injection molding machines are gaining popularity due to their energy efficiency, using 50% to 75% less energy than hydraulic machines. The market is shifting towards all-electric machines, which save up to 70% of energy compared to hydraulic machines and provide better acceleration performance and repeatability. However, the global plastic injection molding machines market is dominated by hydraulic machines as of 2032.

“Integrating a high precision dosing system with the IntElect machine and the optimal heat balance attained by the Rico dual tip nozzle delivery system ensures unprecedented distribution of the 15 gram shot weight. The result of the high machine dynamics means that part weight accuracy of 0.059 grams is repeatably replicated in the fastest possible cycle time,” explains Aliyev.

Given that each dental article weighs just 0.425 grams, and with an LSR shot weight of just 1.7 grams, the exhibit features Sumitomo (SHI) Demag’s smallest IntElect injection unit. An LSR eTwin Connect from Reinhardt-Technik delivers material to the needle gate nozzle tool. Material is then injected into each of the four cavities twice. Metering data directly connects to the IntElect processing data via OPC-UA, ensuring a fully traceable and stable production process.

LSR tooling specialist RICO supplies the 256-cavity open tool system. The Elastosil LR 3844/50 material from Wacker Chemie is dispensed via a sophisticated yet compact Industry 4.0-ready LSR eTwin Connect dosing system engineered by another LSR expert - Reinhardt-Technik. This metering and static mixing system guarantees the perfect mixing ratio of two additives, ensuring 99.75% of the LSR material is processed.

LSR is regarded as a unique material, in that it remains flexible and elastic down to -50°C, yet also retains its properties up to 200°C. As a result, LSR is used extensively in electronic components, cables etc. where insulation is required, as well as in medical and healthcare products and the consumer goods sector. To support these markets, in the last five years Sumitomo (SHI) Demag has made significant investments developing an all-electric LSR package that inevitably delivers the cleanliness and precise shot control required to handle this low viscosity material. This year’s Fakuma exhibits demonstrate the company’s advanced proficiency in moulding high-specification LSR components, exclaims Aliyev.

The eTwin servo-driven piston pumps save processors up to 80% energy compared to air-driven pumps. While the integrated cooling system and pulsation-free volume flow helps to optimise the filling behaviour and prevent the LSR material from curing too soon. The unit also performs automatic venting, purging air from the material before it is fed into the moulding machine and tool. Combined with the IntElect’s high injection dynamics, the repeatable process ensures the highest component quality is achieved time and time again.

In terms of plastic injection molding machines market leadership, the United States stands out as one of the leaders, with approximately 20,000 plastics processors employing around 1.5 million workers. This dominance is further evidenced by the hybrid injection molding machine's status as the second fastest-growing machine in the market, highlighting the integration of hydraulic systems with advanced technologies. These factors collectively underscore the dominance of hydraulic IMMs in the plastic injection molding market.
