Evo-Tech Rigid Chain Technology Solution – Automatic Mold-Change Equipment
Automatic Mold-Change Equipment
"The revolutionary 'rigid transmission + flexible storage' design addresses the core pain points of automatic die-changing equipment in heavy-load, high-speed, and compact applications."
Industrial scenarios
In the modern field of intelligent manufacturing, the ability of production lines to rapidly respond to market demands and achieve flexible, multi-variety, small-batch production has become a core competitive advantage. As a critical component in realizing this goal, automatic mold-changing equipment enables molds to be swapped and precisely positioned in just minutes—or even tens of seconds—significantly reducing production preparation time. During the mold-changing process, the rapid translation, stable support, and exact positioning of the mold place exceptionally high demands on the rigidity, load capacity, operating speed, and reliability of the drive system. Traditional drive solutions often struggle with insufficient rigidity, complex installation and maintenance, and bulky footprints when handling large travel distances under heavy loads, thereby limiting the full potential of automatic mold-changing systems. However, the innovative application of rigid-chain lifting technology in the automatic mold-changing sector addresses these efficiency bottlenecks of conventional methods through an integrated electromechanical design approach.

Background Challenge
- The contradiction between overload and insufficient rigidity: Mold weights often reach several tons—or even tens of tons—while conventional transmission components tend to deform under heavy loads, leading to reduced positioning accuracy (with errors potentially exceeding 0.1 mm) and ultimately compromising the stability of product quality.
- Constraints of space and efficiency: Traditional transmission systems require additional guiding and supporting components, resulting in bulky equipment that struggles to fit into compact workshop layouts. Meanwhile, conventional solutions typically operate at speeds no faster than 1 m/s, making it challenging to reduce the mold-change cycle below 30 seconds.
- Maintenance Costs and Downtime Risks: Traditional transmission components suffer from meshing clearances, lubrication requirements, and wear in vulnerable parts, leading to frequent maintenance needs—such as scheduled shutdowns every 3 months for inspections. Moreover, unexpected failures often result in complex repairs, potentially causing costly production line downtime. Industry statistics show that a single unplanned equipment stoppage can lead to losses amounting to tens of thousands of yuan.
- Poor adaptability to harsh conditions: The die-changing area may contain oil stains, dust, and metal debris, making traditional transmission components susceptible to contamination—leading to jamming or corrosion—and ultimately shortening the system's lifespan.
Evo-Tech Rigid Chain Technology Solution
01.High-Precision Transmission Module with Overload ProtectionCore structure: Features forged chain links made from high-strength alloy steel, with rigid connections between links that eliminate any gaps—achieving repeat positioning accuracy of up to ±0.02mm during transmission. Load Capacity: A single rigid chain can handle axial loads ranging from 5 to 200 kN (depending on the model), and multiple chains can be combined in parallel to meet even heavier-load requirements. |
02.Highly efficient and compact integrated designSpace Optimization: The chain links can be folded and neatly stored in a compact chain case (with a storage length that’s just 1/10 of the fully extended length), eliminating the need for additional guiding components. As a result, the device occupies over 40% less floor space compared to conventional designs. High-speed responsiveness: The drive motor is directly connected to the chain mechanism, achieving a transmission efficiency of up to 98%. It can operate at speeds as high as 300 mm/s, and when paired with a servo control system, it enables stepless speed adjustment—significantly reducing mold-change cycles. |
03.Maintenance-free and long-lasting featuresSealed Protection: Fully enclosed chain box design + self-lubricating bearings ensure stable operation even in oily or dusty environments—no additional lubrication required. Durability: The chain link surfaces are hardened, ensuring a fatigue life of up to 1 million cycles with a low failure rate. |
