Product Selling points
High-Performance 90-Ton Clamping Force
The Haitian 90-ton injection molding machine offers precise clamping for small and medium molds. It produces high-quality plastic items consistently. Factories achieve stable output for electronics, household goods, and packaging materials. Teams rely on the machine for efficient mass production without quality fluctuations.
Energy-Efficient Servo Motor System
The advanced servo system reduces energy consumption by 20%-80% versus hydraulic machines. It optimises power usage for long production cycles. Manufacturers cut operational costs while minimising environmental impact. The system maintains stable pressure, fast injection, and smooth operation during intensive production.
Reliable Second-Hand Machine Inspection
Every unit undergoes a comprehensive inspection for servo performance, hydraulic components, and injection stability. On-site testing is available for buyers to verify performance. Teams confirm compatibility and functionality before purchase. This reduces risk and ensures confidence in second-hand investments.
Versatile Application Scenarios
The machine suits electronics components, household plastic parts, and small containers. It handles multiple product types with high precision and repeatability. Factories expand production lines or replace older machinery efficiently. The Haitian 90-ton machine balances versatility, reliability, and energy savings.
