Why Does Ultrasonic Welding on Plated Plastic Often “Fail on the First Weld”? – In-Depth Analysis & Practical Solutions-Ⅱ
Our approach: · Step 1: Soft-start low-energy vibration — welding begins with lower amplitude and power. The goal is to “gently” break through the resistance of the plating layer, rather than impacting it violently. · Step 2: Progressive energy output — after the plating layer’...Read more -
Why Does Ultrasonic Welding on Plated Plastic Often “Fail on the First Weld”? – In-Depth Analysis & Practical Solutions-Ⅰ
1. Common Failure Phenomenon: Good Surface, Weak Inside Many manufacturers encounter a puzzling issue when ultrasonic welding plated plastic parts: · Immediately after welding, the appearance looks normal — the weld seam is neat, and the plating layer appears intact; · However, duri...Read more -

How to Solve the Most Troublesome Problems of PP Plastic: False Welding, Cold Welds, and Air Leaks—Ⅰ
Combining the inherent defects of PP—semi-crystalline, high elasticity, strong shock absorption, and extremely narrow welding window—this guide provides targeted solutions from six dimensions: 【Product Structure Design → Material Formulation → Equipment Configuration → Process Parameters → Fixtu...Read more -
How does an ultrasonic welding machine actually weld plastic?
First, let’s discuss the principle of ultrasonic welding machines: They convert 50/60 Hz electrical current into high-frequency electrical energy (such as 15, 20, 30, or 40 KHz) through an ultrasonic generator. This electrical energy is then transformed into mechanical motion of the same fr...Read more -
