Rubber Injection Molding Machine for Glass Encapsulation

Characteristics

As one of the most demanding automotive windows in terms of sealing, triangular windows require exceptionally precise manufacturing processes. With the rise of new energy vehicles, manufacturers are placing even higher demands on the sealing performance of triangular windows to enhance interior comfort and reduce noise.

Dekuma, a high-end rubber machinery manufacturer, continues to explore new technologies and materials in the niche field of sealing strip processing equipment, enhancing the efficiency and precision of its glass encapsulation machines.

This automobile rubber parts making machine leads the industry in several key areas, offering a turnkey solution for automotive manufacturers:

▪ Quick Material Changing

Equipped with an advanced FIFO (First-In-First-Out) vertical injection unit, the machine allows for fast material changeover by enabling quick replacement of the injection chamber material.

▪ Easy Operation

To prevent displacement during mechanical operation, Dekuma’s glass encapsulation machine adopts a fixed lower platen and moveable upper platen, with four-column clamping that ensures even force distribution. The low working platform enhances operational efficiency, improving both production output and product quality.

▪ High Precision

Triangular windows consist of multiple components, and the encapsulation process demands precise control of the injection volume to ensure consistent product quality. This Rubber Injection Molding Machine for Glass Encapsulation uses a patented injection structure, servo motor pump, and hydraulic control system to deliver high repeat injection accuracy. The result is greater reliability, less material waste, and higher yield—just what automotive parts injection molding companies need to meet growing demand for precision.

▪ Energy Saving, Low Operating Cost, and Low Noise

The servo system output is dynamically adjusted to match the required pressure and flow, reducing energy consumption by up to 60% compared to traditional proportional pressure and flow control methods. This cuts operating costs while maintaining low noise during operation.

Application

In traditional rubber injection molding processes, it’s common to first mold the TPV thermoplastic elastomer and then manually attach the rubber sealing strip around the glass edges. The Dekuma glass encapsulation machine integrates the entire process by encapsulating the glass and injecting the TPV sealing in one step, ensuring a perfect seal for automotive triangular windows.

In addition to TPV, this glass encapsulation machine is also compatible with TPE, flexible modified PVC, and other injection-moldable raw materials.

It is widely used in the automotive glass encapsulation industry, particularly for large-size car windows with integrated TPV edge sealing. On top of technical excellence, Dekuma offers a smooth experience in terms of after-sales service, maintenance support, and overall cost-performance ratio, making it a reliable partner for your automotive parts production needs.
