What are the Benefits of Silicone Injection Molding?

The silicone injection molding process has become one of the most sought-after production processes for a spectrum of industries because it enables the manufacture of top-quality, high-precision silicone parts through the use of diverse properties explicitly required by the customer. This blog centers on the many benefits of silicone injection molding and what makes it so appealing to those desiring to produce custom-made silicone products.

What is Silicone Injection Molding?

This manufacturing method injects liquid silicone rubber into the mold cavity at high pressure, then cures and solidifies it within the mold. After curing, the finished silicone part can be ejected from the mold. This process unveils several efficiencies, repeatability, and the possibility of geometry complexity.

Silicone Injection Molding

There are many reasons why silicone injection molding is the best process for producing custom silicone products. Let’s have a look at these benefits:

• Exceptional Versatility: Silicone, with its induction properties, lends applicability to diverse product segments. Due to its flexibility, heat, chemical resistance, and biocompatibility, silicone has become quite versatile. On this count, it makes it possible for manufacturers to supply custom parts that are sensitive to design for their applicability in a range of industry sectors like medical, automotive, electronics, and consumer goods.
• High Precision and Repeatability: It is a very accurate manufacturing process. The use of precision-engineered molds guarantees the exact dimensions and tolerances for parts in each run of production. This is crucial in cases where tight tolerances are required, ensuring great functionality in various applications.
• Faster cycle times: LSR’s cycle times are much quicker than all other molding techniques. This is because LSR cures very rapidly within the mold, resulting in faster production and increased output. Therefore, faster cycle times achieve lower production costs and quicker turnaround time for custom silicone products.
• Very Low Material Wastage: This process is a closed-loop system, significantly reducing material waste throughout the process. LSR is metered and injected into the mold cavity with minimal residue, resulting in low-cost parts and no harm to the ecological balance.
• Flash-Free Components: This extra material is known as flash and develops at the trim line on the periphery of a molded component. Utilizing well-designed molds and runners, silicone injection molding avoids flash conditions, eliminating the need for trimming or deburring processes for a better manufacturing process.
• Ability to Manufacture Complex Geometries: Flow characteristics of LSR have the potential to mold complex geometries with tight tolerances and undercuts. It provides a unique opportunity for the production of shapes, the basis of which, using more traditional methods of production, would be difficult or even impossible.
• Overmolding Capabilities: This can over-mold silicone onto a wide range of substrates, including thermoplastics and metals, to create composite parts with combined properties. For example, a silicone keypad over-molded onto a plastic housing will yield a soft, tactile surface plus a robust structure.
• Biocompatible Applications: Not many biocompatible grades of silicone exist to meet strict medical device standards, making molding ideal for manufacturing medical-grade components, including gaskets, seals, and implants. Depending on specific biocompatible applications, silicone molding manufacturers can guide the most suitable grades.

Key Considerations of Selecting a Silicone Injection Molding Partner

There are many benefits to injection molding using silicones, and the choice of the manufacturing partner is paramount. Relevant aspects include several things, such as experience with injection molding for complex geometries or demanding applications and material expertise, respecting the capability to recommend the right material for your specific application based on knowledge of various silicone grades and their characteristics.

• Capabilities in Mold Design: A company should be able to design its molds in-house to ensure efficient production and high-quality parts.
• Quality Control: The manufacturer should have a good quality control system that ensures uniformity of the quality of the parts produced according to the specifications.
• Communication and Collaboration: Be able to communicate from the initial idea to the final product. Look for a manufacturer who shares concepts and works with you to achieve results.

Considering these factors, you choose the molding partner who is suitable, professional, and has what it takes in resources to realize high-quality custom silicone products relevant to your needs.
