Dual Hardness Co-Extruded Rubber Seals – Our Professional Co-Extrusion Extrusion Capability

Our factory supplies custom dual hardness co-extruded rubber seals. This solid-sponge composite extrusion combines two durometers in one profile for stable installation and excellent sealing. EPDM is standard, with silicone and CR optional. Suitable for architectural and industrial sealing applications

Our molded production workshop strictly follows standardized housekeeping management. After workers finish their daily shifts, they will thoroughly clean up the workbenches and production areas.

Qingdao Todo Rubber has upgraded its rubber pre‑forming production workflow. Random sampling weight inspections are implemented on extruded rubber blanks prior to compression molding. This standardized pre‑forming procedure reduces material waste, shortens molding cycle times, improves overall production efficiency and enhances batch‑to‑batch quality consistency for custom‑molded rubber components.

Behind every high-quality coloured rubber product is a reliable and consistent rubber compounding process. To meet the growing demand for customised rubber components in different colours, we have established a dedicated coloured rubber compounding workshop for the development and production of custom rubber compounds.

A silicone hose is a flexible, high-temperature-resistant tube used for coolant, air and fluid transfer applications. This article explains silicone hose materials, temperature resistance, reinforcement, applications and how to choose the right silicone hose for automotive, industrial, marine and other demanding environments.

We are thrilled to share great news from our overseas business department: Our company has completed the shipment of a full 20ft general container loaded with customized PVC container door sealing strips this week, marking another milestone in our stable overseas export layout for rubber & PVC sealing products.

Have you ever struggled with low production efficiency and high unit costs for small silicone molded parts? Our factory’s multi-cavity silicone compression molding line perfectly solves this pain point. As shown in the production photo, the multi-cavity mold can form multiple identical bright green silicone parts in a single molding cycle. Integrated with hot-press vulcanization equipment, the one-step molding process cuts secondary trimming workload, ensures consistent size and surface gloss of each silicone workpiece, and greatly shortens mass production lead time for global clients.

Rubber extrusion is a core high-efficiency manufacturing technology in the rubber industry, widely applied in automotive, construction, medical and industrial fields. This article comprehensively introduces the definition, working principle, mainstream products, core advantages, professional equipment, complete production steps and authoritative industry quality standards of rubber extrusion. It also elaborates on standardized quality control measures, helping customers and industry practitioners fully understand the standardized production strength and application value of modern rubber extrusion technology.

To solve the vibration and pressure resistance pain points of heavy industrial equipment, our company officially launches the new 15-ton natural rubber and steel plate composite damping pad. Adopting integrated hot-press composite technology, the product combines high toughness natural rubber and high-hardness steel plate, featuring high load-bearing, wear resistance and stable shock absorption. It provides reliable long-term vibration isolation and buffer protection for engineering machinery, industrial equipment bases and other heavy-load scenarios, further enriching the company’s industrial shock absorption product line.

Recently, our R&D and manufacturing team for rubber sealing products has announced exciting news. For the long-standing industry-wide defect of edge shrinkage during molding on our extra-large heavy-duty O-rings weighing 1 kg apiece, we have completely overcome this technical challenge after multiple rounds of formula adjustment, mold optimization and molding process iteration. This large-size O-ring product can now be stably mass-produced with qualified yields, marking a new milestone in our manufacturing capacity for large-diameter heavy-duty sealing components.

We have fully upgraded our silicone molding workshop to achieve complete in-house production, covering silicone compounding, vulcanization, trimming and packaging. The optimized workflow ensures stricter quality control, stable product performance and shorter lead times. We offer custom silicone molding services according to customer drawings and samples, with full compliance to FDA, RoHS and REACH standards. Multiple functional silicone materials are available to meet food-grade, high-temperature, oil-resistant, flame-retardant and insulating application requirements.
