Ultrasonic welding machines play a crucial role in the production of the casing of the milk warmer. It uses high-frequency vibration to quickly fuse plastic parts, forming a seamless connection. This technology is not only efficient and energy-saving, but also ensures that the welding points are firm and beautiful, avoiding pollution problems caused by traditional adhesives or hot melt. Compared to other methods, ultrasonic welding has fast speed and low cost, making it particularly suitable for mass production, making the outer shell of the milk warmer more durable and in compliance with environmental standards.

However, once the fixing screws of the mold become loose, the problem arises. This can lead to inaccurate welding, deformation or cracking of the shell, directly affecting product quality.
Therefore, this article analyzes the reasons for loose screws in SONICS ultrasonic welding machines from a product perspective, and provides you with a systematic fault diagnosis and maintenance process.
The main reasons for looseness include three points:
Firstly, prolonged high-frequency vibration of the equipment can easily cause screws to loosen due to fatigue;
Secondly, if the screws are not tightened or low-quality materials are used during installation, they are easily affected by thermal expansion and contraction;
Thirdly, insufficient daily maintenance, such as not regularly checking or lubricating, accelerates wear and tear. These problems may seem simple, but when accumulated, they become major hidden dangers.
For this type of malfunction, Welding Ultrasonic has launched a professional repair process:
Online consultation: Customers can describe problems with SONICS ultrasonic welding machines through phone or online platforms to obtain preliminary guidance.
On site inspection: Technical engineers come to inspect the equipment comprehensively and accurately identify the cause of loose screws.
Determine repair plan: Based on customer needs and fault conditions, jointly decide whether to repair and develop a suitable plan to ensure high cost-effectiveness.
Maintenance and debugging: Engineers tighten or replace screws, debug equipment, restore all functions, and put production back on track.
