What is Silicone Molding?Silicone molding is a process used to create parts and products using silicone rubber. Silicone is a highly versatile material known for its durability, flexibility, and resistance to temperature, UV light, and chemicals. This makes it an excellent choice for a wide variety of applications across many industries.In the silicone molding process, silicone rubber is usually heated and then shaped in a mold under pressure. The silicone is then cooled and hardened (a process known as curing), and the finished part is removed from the mold.Here's a brief overview of each step:Step 1: Preparing the SiliconeSilicone comes in various forms, such as high-consistency rubber (HCR) or liquid silicone rubber (LSR). The silicone might need to be mixed with additives or colorants to achieve the desired properties and appearance.Step 2:MoldingThe silicone is placed in a mold usually made of metal. The mold is designed to have the exact shape of the desired part.Step 3:Heating and CuringThe mold is heated to cure the silicone. The heat causes the silicone to transform from a liquid or a soft solid into a flexible, durable solid. This process can take anywhere from a few seconds to several minutes, depending on the size and complexity of the part and the specific type of silicone used.Step 4:DemoldingThe part is removed from the mold once the silicone has fully cured. This can sometimes be done by hand, but machines are often used for larger production runs or more complex parts.Step 5:Post-Curing and FinishingSome silicone parts may require post-curing, a process in which they are heated again to ensure full curing and to improve certain properties. The parts may also be trimmed or finished to remove excess material and ensure they meet the necessary specifications.The specific process used can vary depending on the method of silicone molding chosen (such as Compression Molding, LSR Injection Molding, overmolding, Dripping Dispensing Molding or Extrusion Molding injection molding), as well as the type of silicone used and the specifications of the part being created.2. Silicone Compression MoldingCompression molding is a well-established method for manufacturing simple silicone rubber components. It is a straightforward process that involves high pressure and heat to transform vulcanized silicone rubber into a durable, functional rubber part. The silicone rubber is placed in an open mold, closed, and subjected to significant heat and pressure. This forces the casting material to fill all areas of the mold and expel any trapped air. The heat and pressure are maintained until the material is fully cured. Once the parts have been cured, the silicone products are removed from the mold.Compression molding suits applications requiring low durometer and tight tolerances, especially when injection molding costs are prohibitive. With over a decade of experience, our team possesses the expertise to create relatively intricate parts using compression molding techniques.AdvantagesMinimal lead time: Short set up a timeEasy to prototype: Minimal wastageWidest range of part sizes: Perfect for the manufacturing of parts with a very large cross-sectionDimensional stability: Capacity to process stiff, high durometer materials, Excellent for low quantities of parts requiring a long cure timeLow tooling and equipment costs: Tooling is simpler and more cost-effective than injection molding, Although this technique has a longer cycle time, it is a low-pressure mold, which means it’s inexpensive to produce a variety of cavities without high tooling costs.ApplicationsHome&housewares & Appliances ( Kitchen & dining&table & Drinkware &household.etc.)Baby & Toys (Baby products, feeding products, and learning toys.）Health & Beauty & Personal Care （Oral care & Beauty tools/Accessories & hair care, etc.）Stationery & Office Products(Arts & Crafts& School products & Office products etc. )Sports & Outdoor & Garden ( Sports and fitness & Travelling & Outdoor portable or silicone water bottles etc. )Pets SuppliesElectronic & Cell Phones Accessories ( Protective cover& Case, holder, etc.)Automotive & Aerospace & MilitarySmoking productsPromotional products (Licensed products & Mascot & Blind box products)3.

Silicone OvermoldingSilicone Overmolding, also known as Rubber Overmolding or Liquid Silicone Rubber (LSR) Overmolding, is a sequential injection molding technique where multiple components are molded together, one layer atop another. This process is often described as two-shot molding, signifying its two-stage nature.High-temperature-resistant thermoplastic materials such as PC, PPSU, PA + GF, and PBT are secondary molding materials. On the other hand, the primary overmolding material is commonly silicone (either high-temperature vulcanizing silicone or low-temperature vulcanizing silicone) or liquid silicone rubber (LSR). Compared to assembled or bonded parts, silicone overmolded components exhibit superior quality.AdvantagesDesign: Multi-Material.

Silicone Dripping Dispensing MoldingSilicone Dripping Dispensing Molding is a specialized process that uses highly durable and adaptable silicone to create various products with precision and detail. This technique involves dispensing a liquid silicone into a mold, which then hardens or "cures" to take the shape of the mold.This process differs from other moulding types due to silicone's unique properties. Silicone can withstand high temperatures, is resistant to many chemicals, and has excellent electrical insulation properties, making it a great choice for a variety of applications. The "dripping" or "dispensing" refers to the method of application, where the liquid silicone is carefully and precisely dispensed into the mold.This allows for much control and precision in molding, making it possible to create intricate designs and shapes that may be difficult or impossible to achieve with other materials or methods. Once the silicone has been dispensed, it is left to cure, solidifying into the desired shape. This makes Silicone Dripping Dispensing Molding an innovative and powerful technique in the field of manufacturing.AdvantagesDesign: Multi-colored.

Silicone Extrusion MoldingSilicone extrusion molding creates long, continuous shapes made from silicone materials. Unlike other types of molding, such as injection molding, extrusion molding is typically used to produce shapes that have a consistent cross-sectional profile, like tubes and rods, cords, seals, gaskets, strips, sheets, and custom profiles. This process involves feeding raw silicone into an extruder, which applies heat and pressure to soften the material. The softened silicone is then forced through a die, giving it its final shape. After the silicone is extruded and shaped, it is cured or vulcanized, causing it to harden and take on its final properties. The key features of extruded silicone include its excellent thermal stability, resistance to UV and ozone, flexibility, and biocompatibility. These properties make extruded silicone suitable for a wide range of applications in various industries, including medical, food and beverage, aerospace, electronics, automotive, and more.AdvantagesExtrusion molding also comes with its own set of advantages.The continuous process can produce lengths of up to 60 feet;Consistent cross-section results in the production of complex shapes;High production volumes;Low cost per pound of materials used;Good for producing tube-shaped products such as pipes and hoses.ApplicationsSilicone Rubber Extrusions is a highly effective manufacturing process employed to create long, continuous silicone components with a constant cross-sectional profile. Utilized in a wide range of industries, this process harnesses the unique properties of silicone rubber, renowned for its flexibility, resilience, temperature resistance, and biocompatibility, among other beneficial attributes.Silicone Rubber Extrusions are used to manufacture a broad spectrum of products, including seals, gaskets, tubing, cords, profiles, and strips, among others. Thanks to the process's adaptability, these products can be designed with a variety of cross-sectional profiles and dimensions, from simple round cords to complex custom profiles.In short: Silicone extrusion molding is widely used in simple silicone objects.7.
