One-Stop Silicone Tooling Process

Tooling, also known as mold, refers to the cavity space into which material is compressed or injected to get a finished part. Effective tooling is essential for producing high-quality products. It extends product life cycles and ensures the proper functionality of manufactured goods.

As the backbone of silicone molding, the quality of the tooling directly impacts the performance and reliability of the final product. As a professional manufacturer of silicone products, OTI brings extensive experience and expertise in tooling services. Our team works closely with customers to gain an in-depth understanding of their specific needs, enabling us to develop innovative and customized tooling solutions that meet and exceed expectations.

STEP 01 Collaboration

A detailed report about issues and improvements will be delivered after an in-depth understanding of customer’s needs and application.

STEP 02 Quotation

A reasonable and competitive price will be quoted once confirming the design.

STEP 03 DFM Report

DFM report delivers feasibility insights and risk identification, effectively reducing defect rates and minimizing later tooling rework.

STEP 04 Tooling Manufacturing

One-stop integration service delivers rigorous tooling tolerance management, process alignment, and real-time data collection.

STEP 05 Sampling

Record all core data throughout the sampling process, and sort out the qualified samples for customer testing.

STEP 06 FAI and sample approval

Inspection documents will be provided in accordance with the customer's drawing. A third-party test report can also be supplied upon request.

STEP 07 Pilot production and process finalization

We will optimize the molding parameters through several pilot runs and make ongoing adjustments to reach a top-tier yield rate.

STEP 08 Production Ramp-up and Capacity Scaling

Integrated injection-vulcanization lines enable flexible small-batch production and on-demand capacity scaling, closing the gap from tooling to mass production.

In-House Silicone Mold Design Capabilities

Our experienced and skilled design team works closely with clients to gain a thorough understanding of their requirements through in-depth communication. After conducting a comprehensive analysis of appearance, structure, function, performance, and other key factors, we develop customized tooling solutions to guarantee precision and production feasibility.

Design Plan

Conduct a thorough analysis of customer requirements for appearance and structure based on practical application scenarios. Optimize the design in line with customer standards and product positioning to ensure both aesthetic appeal and reliable performance. Develop a solution that meets expectations while ensuring all proposals are reasonable, practical, and executable.

Function and Performance Design

Focus on functional performance by combining material properties and process requirements, aiming to ensure reliable stability in operation. Drive product performance by carefully selecting suitable silicone materials, optimizing structural designs, and fine-tuning manufacturing processes to achieve superior functional outcomes.

Tooling Structure Design

Balance cost and performance by evaluating manufacturing processes, materials, and production expenses. Develop a stable, well-engineered tooling design that aligns with product appearance and structural goals, guaranteeing that the product shape, dimensions, and surface quality consistently meet customer expectations and that the tooling offers long service life and stable performance.

Customized Tooling Solutions (Cavity Options)

The design of the tooling cavity is a critical factor in determining production efficiency and part quality, as it directly influences processing speed, manufacturing cost, and output consistency. We recognize that customers prioritize flexibility and efficiency in both product development and volume production. To better meet these needs, we offer different tooling cavity options.

Single-Cavity Tooling (Prototyping)

Single-cavity tooling is typically used for prototyping, with a lead time of approximately 7–10 days. Producing one part per cycle, it offers a low-cost, quick-turnaround solution that supports rapid sampling and small-scale production. This helps customers minimize upfront investment while enabling trial runs and market testing.

Multi-Cavity Tooling (Volume Production)

Multi-cavity tooling, as the term implies, features multiple cavities and produces multiple identical parts per molding cycle. Constructed from high-strength hardened steel, the tool is designed to withstand repeated production cycles. It delivers high throughput and significantly reduces the cost per part at large production volumes.

Family Tooling (Assembly Sets)

Family tooling contains multiple cavities, each designed to produce a different part in the same molding cycle. This differs from single-cavity tooling (one part per shot) and multi-cavity tooling (multiple identical parts per shot). Family molding is especially valuable for assemblies where multiple parts are always used together. By integrating these parts into one tool, we can produce complete assemblies more quickly and at a lower cost.

Silicone Molding Tooling Types

Customer projects vary by size, complexity, design, quantity, purity, precision, and many other factors. The resulting parts may feature indentations, lips or ridges, holes or notches, grooves, and other kinds of cavities within the tooling. The projects might call for a small quantity of something large or a big amount of something tiny. Our dedicated engineering team is committed to delivering innovative, tailored solutions that precisely meet your specifications.

Compression Tooling

A compression tooling is a matched metal die set comprising a cavity (female) and a core (male). The tooling closes around the preheated charge, applying heat and pressure to form the material into the final solid shape. Characterized by its straightforward construction and cost-effectiveness, this tooling type is particularly appropriate for materials that demand high density or elevated hardness, and is well-suited for medium- to large-scale components such as silicone gaskets, silicone seals, and silicone mats. Furthermore, it accommodates a broad range of rubber compounds, including those that are challenging to process.

Injection Molding Tooling

Unlike compression tooling, which relies on open filling, LSR injection tooling employs a closed injection system operating under high pressure. In addition to the tooling base, core, cavity, inserts, and slides, the system integrates a runner network, valve gating, and temperature regulation. This configuration delivers high automation and precision, making it ideally suited for large-scale, high-accuracy production, such as medical parts and baby parts. Moreover, to optimize cost and throughput, we are capable of operating one cavity with two cores per single cycle, leveraging the capabilities of our LSR injection equipment.

Preguntas frecuentes

How could we get the best silicone product quality?

Optimal silicone product quality comes from the right synergy of product design, tooling design, molding equipment, and material selection.

How long do you need to make a compression mold tooling?

Tooling lead time varies by complexity: simple designs (cavity and core only) take 7–12 days, while complex designs with sliders and ejection systems require 15–30 days.

What are the key reasons that LSR injection molding tooling costs substantially more than compression mold tooling?

Compared to compression mold tooling, which typically requires only a cavity and core, LSR injection molding tooling is far more complex. It consists of multiple components, including a mold base, mold core, cold runner, cold nozzle, heating tubing, ejector plate, return pins, and other auxiliary parts.

Can you support prototype LSR injection molding Tooling?

Yes, we offer prototype LSR injection tooling. A standard mold base can be used for fast, cost-effective production. For less precise parts, we can also use irregular compression molding with liquid silicone material.

How can we ensure that the tooling meets our requirements?

We'll supply a DFM report for your approval based on the final drawing, covering surface finish, parting line, cavity layout, number of cavities, draft, and gating. We can also make a prototype tool to verify feasibility if needed.

Are you able to support manufacturing using our existing tooling?

Yes,we could produce the part by using your existing tooling .Please send us the tooling drawing and tool photos before quoting.
