Boost Production Efficiency with the Over Molding Process — Free Sample in 48 h

Precision‑engineered over molding process for medical devices, consumer electronics, and automotive seals. Tailored for Corporate Purchasing Managers who demand ROI, speed, and uncompromised quality.

Why Your Current Supplier May Be Holding You Back

1. High Price, Low Yield – Many overseas factories charge premium rates but deliver 30‑40 % higher scrap due to inconsistent curing.
2. Slow Delivery Speed – Lead times of 8‑12 weeks cripple product launches, especially when you need high‑speed delivery for seasonal demand.
3. Quality Inconsistency – Variations in silicone hardness (Shore A 30‑70) cause sealing failures, leading to warranty claims that can rise up to 25 % of total sales.
4. Expensive Shipping & Customs – Heavy, bulk shipments from China increase freight costs by 15‑20 % and introduce unpredictable clearance delays.
5. Lack of Technical Support – No on‑site engineers to assist with mold design, material selection, or process optimization.

According to the Grand View Research LSR market report (2023), the global LSR market will reach USD 4.97 billion by 2030 – a clear sign that demand for high‑quality over‑molded components is soaring. If you can’t keep pace, you risk losing market share.
