Professional Glossary of Liquid Silicone Products & Molds (CN/EN/JA)

In R&D, prototyping, mass production and international business communication related to liquid silicone rubber (LSR) products and molds, consistent terminology is the foundation of efficient collaboration. Chinese, English and Japanese project documents, customer complaints and drawing annotations often differ in translation, leading to misunderstandings, mold modifications, higher costs and delayed delivery. To address this, we have compiled a systematic trilingual glossary of high-frequency terms in the LSR product and mold industry, organized into six categories - materials, processes, molds, defects, inspection & standards, and products & applications - with Chinese, English and Japanese equivalents, for engineers, purchasing and sales teams to reference directly in daily work.

1. Material Terms

Material selection determines product performance and cost. Terms such as LSR, hardness, curing system and temperature rating appear frequently in specifications and MSDS documents. Understanding them accurately is the first step in material selection and formulation communication.

2. Process Terms

Process parameters directly determine molding quality. Injection pressure, mold temperature, curing time and overmolding are core vocabulary in machine setup, trial runs and FAI reports; trilingual alignment reduces translation ambiguity in process documentation.

3. Mold Terms

The mold is the core tooling for liquid silicone molding. Cavity, slider, lifter, gate and vent groove are used constantly in mold design reviews and change requests; unified terminology prevents structural misunderstandings.

4. Defect Terms

Defect judgment is the focus of quality control. Flash, short shot, bubbles, sink marks and debonding appear frequently in customer complaints and 8D reports; clear trilingual definitions help quickly identify root causes and implement corrective actions.

5. Inspection & Standards Terms

Inspection standards are the basis for product acceptance. Hardness, peel strength, air leak test, IP rating, aging and salt spray tests correspond to specific test methods; unified terminology facilitates acceptance alignment with domestic and overseas customers.

6. Products & Applications Terms

LSR products come in many forms across industries. Sealing rings, waterproof plugs, protective covers and steel-frame action figure overmolding are used in quotations, drawings and e-commerce materials; a trilingual glossary enhances professionalism in external communication.

This glossary will be continuously updated as new processes, materials and standards emerge. For LSR overmolding, precision mold design and mass production support, please feel free to contact us - we provide trilingual (CN/EN/JA) technical documentation and sample testing services.
