UnionTech Collaborates with HSL Model to Redefine Industrial Manufacturing with Additive Manufacturing Technology

In accordance with a comprehensive understanding of 3D printing technology, Zhejiang Yuyao HSL Model (hereafter referred to as Hai Shuai Ling), specializing in large model production for automotive, hand plates, and other industries, has successfully incorporated nearly a hundred units of UnionTech's RSPro series and Lite series products. This strategic implementation signifies the seamless integration of digital production models.

Since its establishment in 2013, HSL Model has been responsive to evolving market demands. In recognition of the inherent limitations of traditional CNC processes, particularly in addressing the requirements for one-piece molding, high-volume production, and rapid delivery, HSL Model made a decisive shift towards additive manufacturing technology. This strategic move was aimed at transcending the constraints of conventional processes and facilitating a comprehensive digital transformation in manufacturing.

During the exploratory phase of HSL Model's digital transformation, the team prioritized professionalism as a crucial criterion for collaboration. In evaluating various 3D printer brands in the market, UnionTech emerged as a standout choice. With over 20 years of industry experience, UnionTech has consistently innovated in light-curing 3D printing technology, challenging industry norms and positioning its technology and equipment at the forefront of the sector.

UnionTech's RSPro series equipment, including RSPro1400, RSPro1800, and RSPro2100, has proven highly effective in meeting the specific requirements of large-scale industrial production. Designed to accommodate the intricate and expansive structures of one-piece molding, these printers enable enterprises to achieve high-quality batch production. In light of these capabilities, HSL Model's concluded that a partnership with UnionTech, a distinguished developer in professional 3D printing technology, was the optimal choice.

High Precision, Large Build Volume – RSPro1400

The RSPro1400, an industrial SLA 3D printer with large build volume from UnionTech, boasts an expansive molding range of 1400 × 700 × 500 mm. This capability proves instrumental in facilitating the one-piece molding of large-size parts and the efficient batch manufacturing of smaller components for enterprises. Differentiating itself from traditional single laser printing, the RSPro1400 adopts multiple galvanometer scanner 3D printing technology. Featuring built-in dual laser synchronous operation, this innovation leverages precision algorithms and system upgrades to achieve synchronized control of each independent laser. which not only enhances printing speed but also doubles overall efficiency.

Moreover, UnionTech's RSPro series equipment comes equipped with an automatic calibration function, which utilizes a PSD position sensor to capture the real-time position of the laser and a magnetic displacement sensor to track the PSD's position. The PSD sensor is driven by UnionTech’s self-researched carbon fiber coating scraper and the motor on the scraper, enabling the PSD sensor's movement within the device and completing the automatic calibration function. This precise positioning principle eliminates the challenges associated with designing and implementing large-area calibration boards, significantly improving calibration accuracy and flexibility. Combining these features with the advantages of large format and multiple lasers, the RSPro series contributes to efficient batch manufacturing of large-sized products.

Large Build Volume, with Technical Flavors Added – RSPro1800

The RSPro1800 introduces an ultra-large format design measuring 1800 x 900 x 600 mm, offering an upgraded build volume that enables the production of daily molds in a single pass without the need for splicing. The innovative carbon fiber-coated scraper design, operating in an up-and-down motion as opposed to the traditional left-to-right approach, significantly reduces the scraper's back-and-forth movement distance. The design enhancement not only boosts daily printing speed but also facilitates material recycling, contributing to cost reduction, improved quality, and efficiency in industrial production. Moreover, this approach makes the production process more energy-efficient and environmentally friendly, playing a crucial role in model manufacturing across various industries.

To address model quality and stability challenges in multi-laser high-efficiency production, UnionTech's RSPro series equipment incorporates China's first splicing scanning algorithm, which seamlessly splices together the two sides of the same molded part scanned by adjacent galvanometer scanners, increasing the contact area between the two sides. This ensures excellent mechanical properties of the molded part in the spliced area. The unique 'cross-splicing' technology guarantees the surface quality of molded parts in the splicing area and ensures the mechanical properties of the spliced area, which are essentially on par with the independently scanned molded parts by the same galvanometer (more than 90%).

A robust assurance of technology and equipment enhances the compatibility of materials in daily production, resulting in superior printing effects. HSL models encompass high-temperature resistant and high-toughness materials. The high-temperature resistant materials exhibit resilience up to 260℃, primarily employed in crafting robust, durable, and precisely detailed parts. Meanwhile, high-toughness materials, characterized by high elongation at break and impact strength, prove especially suitable for producing functional verification models.
