How to improve production efficiency of turntable foam injection molding machine production line? Achieve mass production?

1. Collaboration between rotary table and multi-mode position
The characteristic of turntable foam injection molding machine production line is its rotary mold platform design. This innovative structural design has changed the linear production mode of traditional injection molding machines. The precision-machined turntable platform is usually equipped with some independent stations, each of which can be installed with molds of different specifications, and accurate positioning is achieved through servo motor drive. This design enables injection molding, cooling, mold opening, and part removal to be carried out simultaneously, reducing the non-production time in the traditional injection molding cycle. Compared with traditional single-station injection molding machines, the effective production time of the turntable design has been improved.

The multi-mode temperature zoning control system is the key to stable foaming quality. Each mold station is equipped with an independent temperature control module, and the PID algorithm is used to accurately control the mold temperature within the set value ±1℃. In view of the special requirements of the foaming injection molding process, the system can realize differentiated temperature control in different areas of the mold. This temperature control not only optimizes the uniformity of foaming, but also shortens the cooling time, further improving production efficiency.

2. Design innovation of foaming and injection molding
The core competitiveness of the turntable foaming injection molding machine production line lies in its integrated application of supercritical fluid (SCF) foaming technology. The gas injection unit injects CO₂ or N₂ into the plastic melt under supercritical conditions to form a uniformly distributed micro-nuclear bubble structure. The precision metering system controls the gas injection amount with an accuracy of ±0.5%, and cooperates with the multi-stage temperature control of the screw plasticizing system (accuracy ±1°C) to ensure the ideal dissolution state of the foaming agent in the polymer matrix. This microporous foaming technology can reduce the weight of the product by 15-30%, while improving the mechanical strength and dimensional stability, and is suitable for the production of lightweight automotive parts.

Multi-stage injection control technology meets the molding needs of complex foamed products. The high-pressure injection stage (speed control accuracy ±0.1mm/s) ensures that the melt quickly fills the mold cavity; the pressure holding stage compensates for material shrinkage through an adaptive algorithm; the foaming expansion stage accurately controls the decompression rate and expansion space to obtain an ideal cell structure. This multi-stage control capability enables the same production line to produce a variety of products from dense structural parts to high-foaming rate cushioning materials, improving the process adaptability of the equipment.

3. Industry application and economic benefits
The successful application of the turntable foaming injection molding machine production line in various industries has verified its value. The turntable foaming injection molding technology can meet the comprehensive needs of various industries for material performance, production efficiency and cost control.
Compared with traditional injection molding production lines, the turntable foaming injection molding solution shows all-round advantages. In terms of production efficiency, its output per unit time can reach 3-5 times that of traditional equipment; in terms of product quality, the foamed products have both lightweight and high strength characteristics, and good dimensional stability; in terms of economic benefits, the production line can usually recover the investment difference within a certain period of time through the advantages of material saving, energy consumption reduction and manpower reduction. This technology provides greater freedom in product design, allowing designers to break through the limitations of traditional injection molding processes and develop more innovative product structures.
