electric injection molding machinesTopstar’s primary core technology for injection molding machines is a discrete intelligent drive. This technology uses a patented integrated drive-and-control algorithm to improve communication response time to 0.125 milliseconds. This technology is primarily used in because each cycle relies on precise coordination between control logic and servo motion.

Traditional hierarchical control systems introduce latency. Instructions need to be transmitted through multiple layers before finally being translated into action. In the injection molding of high-precision products, even minute delays can affect pressure holding, switching, multi-stage injection, and other critical steps. The machine may still operate, but process consistency will decrease. Our discrete intelligent drive control reduces this delay, enabling faster response. In applications with extremely high-dimensional control requirements, such as automotive lighting components and optical product surfaces, tolerance for appearance standards and time errors is extremely low. Electric injection molding machines need to respond immediately and repeatably.

Discrete Intelligent Drive

To achieve a repeatability accuracy of ±0.01mm for the injection molding machine

Achieving repeatability of ±0.01mm under discrete intelligent drive control is directly related to product quality. If the injection position changes significantly in each cycle, material flow, filling performance, and the stability of the final part will all change. An injection molding machine for precision molding must maintain a stable injection position, ensuring that material enters the mold under the same conditions each time. Premature or delayed switching during holding pressure changes and multi-stage injection can lead to problems such as flash, shrinkage marks, short shots, or dimensional instability. Higher repeatability controls these critical steps.

Suitable for automotive lighting components and optical parts applications

Injection molding machines employing discrete intelligent drive technology are suitable for applications with extremely high requirements for dimensional stability and surface quality, such as automotive lighting components and optical parts. These applications require stable pressure control, repeatable position control, and rapid stage switching response. In the automotive lighting industry, lamp components demand excellent appearance quality and precise shape control. If the electric injection molding machine injects too forcefully, flow defects may occur in the parts; if the holding pressure is too weak, significant shrinkage may occur. Injection molding machines with slow or unstable responses cannot effectively address these problems. Discrete intelligent drive improves this situation by enhancing the process’s accuracy and stability.

Core Injection Molding Machine Technology: Central Direct Pressure Clamping

Topstar injection molding machines’ second core technology is the central direct pressure clamping. This design allows the clamping force to act directly on the center of the mold platen, achieving more uniform mold clamping and reducing deformation that may occur in poorly balanced systems. This results in a tighter parting line, less flash, and a higher product yield. Mold sealing depends not only on pressure but also on the uniformity of pressure distribution. Uneven clamping pressure can cause the mold platen to bend or the mold to misalign. Once this happens, flash is more likely to form, and product quality becomes inconsistent. The direct pressure structure reduces this risk by applying pressure more evenly and more concentratedly.

Center Direct Pressure Clamping

Mold Protection and Shape Retention During Long Production Runs

Injection molding machines with a central direct pressure clamping structure offer better mold protection. If the clamping structure cannot effectively support the mold, prolonged pressure can cause the mold to deform. Topstar’s design helps prevent mold deformation under prolonged pressure, thus extending mold life and protecting precision molds. This prevents the molding machine from slowly damaging the mold it relies on, instead supporting the mold’s geometry and helping it maintain its integrity. This ensures greater consistency and smaller quality deviations in each batch of products.

Suitable for Thin-Walled and Deep-Cavity Products

Injection molding machines with a central direct-pressure clamping system are suitable for molding thin-walled, deep-cavity, and dynamically balanced products. It also supports large moduli and wide openings, enabling the flexible production of various types of parts. Many customers’ factories do not produce only one type of product. They may produce thin-walled parts in one order and deep-cavity or large-size parts in the next. This technology allows for the adaptation of unloading robots and injection molding machines to constantly changing mold conditions and product structures, making it more valuable than molding optimized for a single, narrow application scenario. The central direct pressure clamping design allows the molding machine to maintain flexibility without sacrificing stability.
