Servo Hydraulic Injection Machine
90 ton plastic injection machine
90 ton plastic injection machine for small products
This 90-ton servo injection molding machine is a compact, space-saving general plastic molding equipment, specially designed for mass production of all types of tiny small plastic products. It is widely favored by small plastic processing factories, garment accessory workshops, miniature electronic parts manufacturers, toy factories, and daily chemical small parts production plants.
Different from low-precision ordinary injection machines, we optimize the clamping and injection unit to match small-sized precision multi-cavity molds. It effectively eliminates common molding defects, including flash, incomplete filling, product deformation, uneven single-piece weight, and surface scratches during long-hour non-stop continuous production.
This model is perfectly compatible with molds for various miniature plastic items: small plastic fasteners, clothing decorative accessories, mini electronic connectors, tiny toy components, cosmetic mini plastic shells, and disposable small plastic fittings. Every machine undergoes a strict 72-hour continuous full-load running test before delivery. We provide one-stop full production supporting solutions, including custom multi-cavity small molds, industrial chillers, and automatic raw material feeding systems.

Core Advantages
1. Energy Saving Servo Hydraulic Drive System
An independent servo motor and a variable hydraulic pump are equipped. The hydraulic system only outputs pressure when clamping and injecting, with no excess oil overflow during standby. Compared with traditional fixed pump injection machines, it cuts power consumption by 35%~45%. Stable pressure and speed control keep consistent product quality during all-day continuous running.
2. Universal Wear-Resistant Plasticizing Assembly
Standard nitrided wear-resistant screw and barrel, compatible with most common plastic raw materials like PP, ABS, PS, and PE. It resists material carbon accumulation, avoids black spots on finished tiny products, and extends the service life of wearing parts.
3. Balanced Four-Column High-Rigidity Clamping Structure
90-ton balanced clamping force ensures even pressure distribution for all kinds of small multi-cavity molds. High parallel four guide columns prevent mold shifting, effectively reducing flash on miniature plastic products. Smooth and stable mold opening & closing improve overall daily production efficiency for small items.
4. Multilingual Intelligent Touch Control System
10-inch touch screen supports English, Spanish, French, and other mainstream languages. It can store molding parameters of up to 99 sets of different small molds, with segmented automatic control of temperature, injection speed, and holding pressure. New operators can master basic operations quickly with our English operation manual.
