Injection molding is a plastic-forming process widely used to manufacture various parts. The process is characterized by forcing molten material into the mold cavity. Injection molding can be performed with various materials, including thermoplastic and thermoset polymers. Injection molding is a manufacturing process that uses molds to shape plastic or other materials. Injection molding machines use clamps and hydraulics to inject material into a closed mold forcefully.
Mid-sized injection molding plants lose tens, if not hundreds, of thousands of dollars annually due to flash—the thin, excess plastic that seeps through mold crevices. This translates into not only scrapped parts but also rework time to trim parts, premature mold wear, and rejected orders from quality-conscious customers. As a professional injection molding machine manufacturer,… Continue reading How to solve the problem of flash in injection molding?
Injection molding cycle profile optimization, specifically the coordinated control of pressure, holding, and cooling steps, is the most effective tool for production engineers to improve part quality, reduce cycle time, and lower unit cost. Whether you operate a single-unit injection molding line or manage multiple injection molding machines in a single molding facility, optimizing the… Continue reading Injection molding cycle profile optimization: pressure, hold and cooling steps
Achieving consistent injection molding cycle times hinges on translating every variable that influences the cycle—melt quality, cavity filling and packing, thermal conditions, mechanical motion, and material feed—into standardized, measurable, and controllable actions. When you replace manual adjustments and guesswork with closed-loop control, adaptive setpoints, and integrated monitoring, cycle-to-cycle variability decreases and production becomes predictable. Crucially,… Continue reading How to reduce cycle time fluctuations through injection molding control strategies?
In 2025, injection molding will be an intelligent, data-driven manufacturing technology that combines sensors, algorithms, and proven electric drives to achieve scalable, repeatable quality. Topstar’s independently developed all electric injection molding machine controller has moved from the lab to customer production lines.

Maintaining consistent injection molding processes requires precise control of various factors, including mold temperature, injection molding machine settings, and process parameters. First, ensure precise and stable mold temperature using a mold temperature controller. Furthermore, core injection molding machines utilize fully electric machines with intelligent electric drive controls to reduce communication delays during high-speed cycles. These… Continue reading How to ensure the consistency of injection molding process?
Industry data show that the injection molding of precision plastic parts, such as those used in medical product packaging and optical housings, requires tolerances as low as ±0.01 mm. To achieve these levels of performance, we generally recommend using all electric injection molding machines equipped with servo motors and/or linear guides to ensure repeatable performance.… Continue reading Which injection molding characteristics enable high-precision parts?
Understand the setting method of the injection molding machine Injection molding uses a mold to inject plastic into it, heating and to cool it down. Injection molding machines are used in this process. To set the parameters of an injection molding machine, you need to understand the following: How to set the mold temperature The… Continue reading Understand the setting method of the injection molding machine
