High-stability, quick-response, and energy-efficient servo systems drive process upgrades.

Common Challenges in Injection Molding

Injection molding machines are the cornerstone of modern manufacturing, with hydraulic systems serving as both the heart and brain of the operation. However, faced with fierce market competition, stringent environmental regulations, and rising demands for precision, traditional systems are reaching their limits. CML ESG Energy-Saving Solutions empower customers to reduce energy consumption, shorten cycle times, and extend machine life through comprehensive service.

Key Challenges Facing Today’s Production Floors

Hidden Risk about product quality and process precision

Excessive pulsation:
Unstable oil pressure during injection or holding leads to inconsistent mold pressure. This results in uneven filling density and common defects like shrinkage, short shots, and dimensional errors.

Uneven low-speed operation: 
Precision parts and micro-filling require extremely slow, stable flow rates to ensure consistency. Any flow interruptions or jamming at low speeds will compromise the surface quality and dimensional repeatability of the molded parts.

High oil temperature causing process variations: 
Excessive heat lowers hydraulic oil viscosity, causing fluctuations in injection speed and pressure build-up time. This instability prevents operators from locking in optimal process parameters.

Why Better Efficiency Is the Best Way to Cut Energy Waste

Machine inefficiency leads to dual losses: increased energy consumption and slower response times. These factors not only drive up electricity bills but also severely impact production output, resulting in higher overall costs.

Rising electricity costs:
Traditional systems waste a lot of power during standby or pressure-holding. Because the machine keeps running at high energy even when it's not doing much work, electricity bills go up every year.

Long molding cycle:
If the system reacts slowly or doesn't have enough flow, it takes longer to inject and build up pressure. This slow speed slows down the whole production and reduces the total output.

The Growing Demand for Sustainable Business

Rising pressure from CBAM and ESG:
International companies (OEMs) are setting much stricter rules for their suppliers. They now demand better energy efficiency, lower carbon emissions, and full ESG compliance from everyone in their supply chain.

All these trends show that a good hydraulic system is the key to a machine's success. It decides your market competitiveness, production speed, and product quality. CML solution is built specifically to meet these needs.

Injection Molding Trends: The Road Ahead for Hydraulic Systems

The evolving global market for injection molding machines is demanding higher performance and greater optimization from core hydraulic systems.

These trends encompass not only efficiency and quality but also environmental responsibility. Whether it is the high flow rates required for large-scale production, the low-speed stability needed for precision parts, or the growing pressure of ESG and carbon taxes (like CBAM), all these factors are driving equipment toward higher energy efficiency.

The hydraulic system is the power center of the machine and its control capabilities are essential to meet these challenges. Every stage of injection molding, including injection and pressure compensation, relies on precise and stable hydraulic control. This precision is the main factor that determines product quality, production efficiency, and the carbon footprint.
