Liquid Silicone Rubber China LSR injection molding

Product Details: Liquid Silicone Rubber (LSR) injection molding involves mixing two compounds (Part A and Part B) at room temperature, which are then pumped into a hot mold where they cure quickly. LSR is a high-purity platinum-cured silicone with excellent fluidity, used to produce parts with high precision. It is suitable for applications requiring high temperature resistance, chemical resistance, and electrical insulation. LSR parts can be produced in a range of durometers (10 to 80 Shore A) and various colors. The process allows for high-volume production with minimal waste and consistent part quality[2][5][4].

Pros:
– High-volume production with minimal waste
– Consistent part quality due to even distribution of material
– Excellent temperature resistance (-60°F to 400°F)
– Good chemical resistance and electrical insulation
– Low compression set and high tear and tensile strength
– Suitable for intricate and precise parts with smooth surfaces
– Reduced tooling costs and lead times compared to compression molding

Cons:
– Custom colors may require additional hardware costing over $3500
– Tooling design and fabrication require high-temperature resistance and specific…
– Material handling and mixing must be precise to avoid inconsistencies
– Higher initial tooling costs for high-production molds
– Limited to thermosetting properties, meaning parts cannot be melted and reformed

Silicone Rubber Transfer Injection Molding

Product Details: Silicone transfer molding is a manufacturing technique that combines elements of injection and compression molding. It involves loading a two-component silicone rubber into a transfer pot, which is then pushed into a mold cavity under heat and pressure. The process is suitable for producing medium-volume, high-quality parts with intricate details and tight tolerances. It uses high consistency rubber (HCR) or high-temperature vulcanizing (HTV) silicones, and can also utilize liquid silicone rubber (LSR) for precise and detailed parts[1][4][5].

Pros:
– Ensures accurate replication of the mold design with high precision and detail
– Ideal for producing complex shapes and higher volumes of rubber products
– Minimizes material waste and reduces the need for post-production trimming
– Allows for precise control over the amount of material in the mold
– Flexible production runs with short cycle and changeover times

Cons:
– Limited to production runs of up to 10,000–20,000 units
– Requires separate premixing or milling of the base silicone rubber, cure catalys…
– Can result in more waste as the rubber remaining after transfer will cure and ha…
– May not accommodate very large production volumes efficiently

Frequently Asked Questions (FAQs)

Frequently Asked Questions About Injection Mold Rubber Factories in China

What are the main types of rubber molding processes used in Chinese factories?

Chinese rubber factories primarily use several key molding processes: compression molding, transfer molding, and rubber injection molding. Compression molding is great for low to medium production volumes and larger parts, while transfer molding is ideal for more complex products with tighter tolerances. Rubber injection molding is the most cost-effective for high-volume production of small, precise parts.

How long does it typically take to receive a prototype or production mold from a Chinese rubber factory?

The lead time for prototypes and production molds can vary, but generally, you can expect prototype tooling and samples within 7 days and production molds within 14 days. Some factories also offer fast mold design services, such as Design for Manufacturability (DFM) within 24 hours after receiving your drawings.

What are the benefits of using rubber injection molding over other methods?

Rubber injection molding offers several advantages. It is highly consistent, allows for tight tolerances, and has faster production times. This method is particularly cost-effective for high-volume production of small, intricate rubber parts. It also provides better control over pressure, temperature, and material flow, resulting in more precise products.

How do I choose a reliable rubber injection molding company in China?

When choosing a reliable company, look for factors such as years of experience, customer service quality, and certifications like ISO 9001. Check if the company has a diverse product range and experience working with international clients. Also, consider their approach to product design, approval, and production, as well as any additional services they offer, such as post-processing options.

What kind of materials can Chinese rubber factories work with?

Chinese rubber factories can work with a wide range of materials, including various rubber durometers and silicone materials. They can handle everything from standard rubber compounds to medical and food-grade silicone materials. This versatility allows them to produce a broad spectrum of products, from seals and gaskets to medical devices and automotive parts.
