Large industrial seals are prone to deformation in daily handling and testing, leading to inaccurate inner and outer diameter measurement results with traditional caliper tools. To solve this common industry pain point, we have launched a professional accurate measurement solution for large industrial seals. Eliminating manual reshaping operations, the system effectively reduces human and tool errors, realizes repeatable and consistent diameter data, greatly improves inspection accuracy and efficiency, and standardizes batch quality control. We continue to upgrade production and testing processes to deliver high-reliability sealing products for global industrial manufacturers.

This article introduces high-performance EPDM door and window sealing strips, covering their core features including weather resistance, sound insulation, waterproof and energy-saving performance. It also displays complete product specifications, multiple optional models and colors, as well as wide application scenarios and simple card slot installation method, ideal for various architectural doors, windows and glass curtain walls.

Qingdao Todo Rubber Co., Ltd. – As an experienced manufacturer of custom flexible rubber components, we are proud to launch a new thin-wall extra-long rubber bellows to meet the needs of industrial piping and vibration damping applications worldwide.

Recently, our company's independently developed large EPDM O-type sealing ring successfully rolled off the production line. The product has an outer diameter of 494mm, an inner diameter of 440mm, and a wire diameter of 27mm, marking a significant breakthrough in the company's R&D and manufacturing capabilities in the field of large-size special rubber seals.

Adopting a closed-cell foaming structure, EPDM foam sealing strips feature light weight, high toughness, excellent thermal insulation, water resistance, weather resistance and shock absorption. Breaking through the limitations of traditional sealing materials, they are widely applied in packaging, construction, automotive & marine, thermal insulation, sound insulation and moisture-proof fields, serving as high-quality sealing and cushioning materials preferred for industrial and civil applications.

Our company showcases a complete range of custom compression molded silicone products for global OEM & ODM customers across automotive, electronics, food equipment and medical fields.
