Cap Compression Molding Mould
In the evolution of cap manufacturing processes, compression molding technology is increasingly becoming the preferred solution for high-volume production of quality Cap compression mold, thanks to its unique advantages. SINO MOULD, with its deep expertise in mold manufacturing, has successfully applied advanced compression molding technology to various cap productions, offering global clients efficient, energy-saving, and low-maintenance solutions.
Unlike traditional injection molding, the compression process involves injecting a measured amount of plastic into the mold cavity before closing. The material is then filled and shaped as the mold closes. This characteristic makes it particularly suitable for caps that are sensitive to molecular orientation and require superior sealing performance, such as mineral water caps and carbonated beverage caps. SINO MOULD’s compression molds, with their ingenious runner design and ejection systems, ensure clear threads, stable dimensions, and dense internal structures for every cap, achieving perfect sealing.
Choosing SINO MOULD Compression Molds means you benefit from:
Exceptional Sealing Performance
The compression process results in more uniform molecular chain orientation and lower internal stress in the produced caps, delivering outstanding sealing performance and significantly reducing the risk of leakage.
High Efficiency and Energy Savings
Shorter molding cycles and the absence of high injection pressure lead to significantly lower system pressure and energy consumption, saving substantial production costs.
No Runner Waste
The process itself generates no sprue, achieving near 100% material utilization, which saves costs and aligns with green manufacturing principles.
Long-lasting Mold Durability
Molds operate under lower internal pressure, resulting in less wear. Combined with SINO MOULD's high-quality mold steels and heat treatment, the mold service life is greatly extended.
Core Technologies of SINO MOULD Cap Compression Molding Mould
We are committed to translating the potential of compression molding into tangible benefits on our clients’ production lines through precision mold design.
1.Precision Metering Feed System of Cap Compression Molding Mould
The heart of compression molding lies in precise shot control. SINO MOULD molds are paired with high-precision metering pumps or injectors to ensure a constant and consistent amount of plastic is delivered into the cavity each cycle, guaranteeing cap weight stability and molding quality from the source.
2.Unique Venting&Runner Design of Cap Compression Molding Mould
Efficient air evacuation during mold closing is critical. Our molds incorporate optimized venting channels to prevent short shots or burn marks caused by trapped air. Simultaneously, special runners developed for compression molding ensure smooth and steady plastic flow to every corner of the mold.
3. Efficient Cooling & Ejection System of Cap Compression Molding Mould
To match the high-speed production pace of compression molding, the mold’s cooling system is optimized via CAE analysis, with a scientific layout ensuring uniform and rapid cap cooling, shortening the cycle time. The ejection system is cleverly designed to ensure stable demolding of the formed caps without deformation or damage.
Why Cap Compression Molding Mould are the Ideal Choice for Cap Production?
Compression molding technology is reshaping the landscape of cap manufacturing, as its inherent advantages highly align with modern production needs.
For applications like PET caps, compression molding effectively reduces acetaldehyde generation and lowers the cap’s internal stress, making it less prone to cracking. This is particularly suited for food and beverage packaging with stringent requirements on odor and durability.
From energy savings and material savings to eliminating the sprue recycling process, compression technology reduces the comprehensive production cost from multiple dimensions, offering a remarkable return on investment.
SINO MOULD’s compression molds feature robust construction and stable design, enabling perfect integration with high-speed, fully automatic cap production lines. This allows for continuous, stable output of hundreds of caps per minute, meeting your demand for ultimate efficiency.
