TY703 Submerged Filling Machine is a servo hydraulic–controlled filling system designed for automotive rubber bushings. The process is completed under liquid with low-pressure degassing to remove micro-bubbles, ensuring stable internal fluid quality, reliable sealing, and full data traceability for OEM production.

TY703 Submerged Filling Machine

Servo Hydraulic Controlled Filling System for Automotive Rubber Bushings

Product Introduction

The TY703 Submerged Filling Machine is a servo hydraulic–controlled liquid filling system independently developed by Tianyu Machinery for automotive rubber bushings and rubber suspension components.

Unlike traditional vacuum filling equipment, the TY703 completes liquid filling, bubble removal, and press-fit sealing entirely under the liquid surface. A controlled low-pressure degassing process is applied during submerged filling to remove micro-bubbles attached to the product surface, ensuring stable internal fluid consistency and long-term product reliability.

The system is specifically designed for automotive hydraulic bushings, where strict requirements on internal fluid stability, sealing quality, and process traceability are required. With high repeatability, intelligent data control, and servo hydraulic closed-loop regulation, the TY703 is suitable for mass production environments and OEM quality systems.

Application

The TY703 Submerged Filling Machine is mainly used for:

• Automotive rubber bushings

• Rubber suspension components

• T-type bushings

• Tapered rubber products with controlled thread depth

• Hydraulic-filled vibration isolation components

It is widely applied in automotive chassis, suspension systems, and NVH-related components requiring stable liquid filling and reliable sealing.

Core Process Description

Submerged Filling Process

• Filling, press-fitting, and sealing are completed below the liquid surface

• Prevents air entrainment during assembly

• Ensures consistent internal fluid distribution

Low-Pressure Degassing (Bubble Removal)

• A controlled negative-pressure process is applied during submerged filling

• Removes micro-bubbles attached to the product surface

• Improves long-term durability and consistency

Note: This is not a full vacuum filling process, but a localized low-pressure degassing function.
