What Determines Process Fit?
Process selection depends on the product requirements—not only the product name. Use these five factors to narrow down the most relevant manufacturing routes.
Material Combination
Is the product made only from silicone, or combined with plastic, metal, or another substrate?
Detail & Surface Requirements
Does the product require fine textures, complex features, multiple colors, or localized silicone details?
Tooling & Commercial Priorities
Is the project more sensitive to tooling investment, unit cost, development flexibility, or repeatability?
Production Volume
Is the project at prototype, small-batch, medium-volume, or high-volume production stage?

LSR Injection Molding
Liquid silicone rubber is injected into a heated mold to form detailed silicone parts.
- Best suited for
- Complex geometries, fine details, and repeatable production.
- Consider when
- Precision, repeatability, and production scalability matter.
- Key advantage
- Strong repeatability for complex molded parts.
Silicone Compression Molding
Solid silicone is placed into a heated mold and formed under pressure.
- Best suited for
- Thicker, larger, or structurally straightforward silicone products.
- Consider when
- Product size, durability, and tooling economics are important.
- Key advantage
- Versatile for a wide range of solid silicone products.
Silicone Overmolding
Silicone is molded onto a compatible plastic, metal, or other substrate.
- Best suited for
- Multi-material parts, grips, seals, handles, and integrated components.
- Consider when
- Silicone must bond or integrate with another material.
- Key advantage
- Combines materials into one functional part.
Silicone Extrusion
Silicone compound is formed continuously through a shaped die.
- Best suited for
- Tubes, profiles, strips, cords, seals, and continuous sections.
- Consider when
- The product has a consistent cross-section.
- Key advantage
- Efficient production of continuous silicone profiles.
Multi-Color Silicone Molding
Multiple silicone colors are formed into one integrated molded product.
- Best suited for
- Products requiring integrated color zones, patterns, or visual differentiation.
- Consider when
- Color structure must be molded into the product itself.
- Key advantage
- Integrated multi-color appearance without separate assembly.
Silicone Micro-Dispensing
Silicone is precisely deposited onto selected areas for localized details or surface functions.
- Best suited for
- Fine logos, localized textures, small graphics, dots, or controlled silicone placement.
- Consider when
- Only specific areas require detailed silicone application.
- Key advantage
- Controlled localized detail and decorative flexibility.

Frequently Asked Questions
Process fit depends on factors such as product geometry, material combination, required detail, tooling priorities, and expected production volume. A drawing, reference image, sample, or clear application description helps us compare the most relevant routes before discussing the next step.
LSR injection molding is commonly evaluated for complex shapes, fine details, repeatability, and scalable production. Compression molding uses solid silicone and is often considered for thicker, larger, or structurally straightforward parts. The suitable option depends on the product design and commercial requirements.
Overmolding is relevant when silicone needs to integrate with a compatible plastic, metal, or other substrate to create a grip, seal, handle, bonded interface, or multi-material component. Substrate compatibility and bonding requirements must be reviewed for each project.
Multi-color molding integrates multiple silicone colors into the molded product structure. Micro-dispensing places silicone only on selected areas for local details, dots, textures, logos, or surface functions. The choice depends on whether the color or detail is structural or localized.
Silicone extrusion is normally evaluated for products with a consistent cross-section, including tubes, cords, seals, strips, and custom profiles. Profile design, material, dimensional requirements, and order details still need project-specific review.
Useful inputs include a 2D or 3D drawing, reference image or sample, product application, material or performance priorities, estimated quantity, branding or packaging requirements, and the target project schedule if applicable.
