Project application: Thermal insulation nails are special anchors for external wall thermal insulation, which are widely used in building decoration and anchoring of wall thermal insulation houses. It consists of galvanized screws, nylon expansion tubes and fixed discs. According to the thickness of the insulation layer, it is divided into various specifications. It has the characteristics of anti-aging, anti-temperature sudden change, anti-corrosion, cold and heat resistance; strong bearing capacity, strong pressure bearing, good tensile performance; not easy to deform after loading, moisture-proof, slow-vibration, and good thermal insulation. Our company's thermal insulation nail injection molding machine, TH220/SP servo energy-saving injection molding machine, has been unanimously recognized by domestic thermal insulation nail manufacturers and thermal insulation nail distributors for its configuration, stable product performance and perfect after-sales service system that are superior to the same industry. This model is equipped with a servo energy-saving control system. During the injection molding process of the heat preservation nail, the servo energy-saving system makes corresponding frequency output for different pressure flows, and performs precise closed-loop control of the pressure flow, which meets the energy demand of the servo motor for the injection molding machine. Compared with traditional injection molding machines, it can save 30% to 70% of electricity consumption, and further enhance the competitiveness of products.
