JGL Silicone Rubber Products Co., Limited
Silicone Products OEM&ODM Supplier, Since 2010


Welcome to our Engineering Support page, where we provide comprehensive expertise and resources to help you make the most of your silicone-based projects.

At JGL SILICONE, we understand the importance of collaboration and communication throughout the custom silicone product development process. Our service aims to assist our customers during the earliest stages of product ideation, ensuring the design is optimized for both manufacturing and final functional performance.


When you approach us with a new product concept, idea, or preliminary draft without a 3D CAD drawing, we start by establishing a strong collaborative relationship. We work closely with your team to gain a comprehensive understanding of your product needs, component requirements, and overall project goals.

Our experienced engineers act as an extension of your engineering team, providing valuable input on custom silicone part design and engineering optimization. By combining our expertise in silicone manufacturing with your industry knowledge, we can help enhance the overall functionality and performance of the final product.



Design Development and 3D Modeling: After establishing a mutual understanding of the project requirements, our engineers create detailed 3D models of the custom silicone parts using advanced CAD software. These models provide a comprehensive visual representation of the product, enabling clients to easily evaluate and refine the design.

Design Review and Feedback: Once the 3D models are complete, we share the 2D and 3D CAD files with our clients for review. This allows them to thoroughly examine the design from multiple perspectives and provide feedback for any necessary revisions. During this stage, clients can assess:

  • The overall size and dimensions of the silicone part
  • Cross-sectional views from various angles to understand the internal structure and features
  • Realistic renderings that provide a clear understanding of the final product’s appearance and functionality

Design Iteration and Refinement: Based on the feedback received from clients, our engineers make any required revisions to the design, ensuring that the custom silicone parts meet or exceed expectations. This iterative process helps guarantee that the final product is both functional and aesthetically appealing.

Final Design Approval: After incorporating all necessary revisions, the updated 3D models are shared with clients for a final review. Once they approve the design, the project moves forward to the next stage, which involves mold making and production.


In the development of custom silicone products, implementing Design for Manufacture (DFM) principles is crucial for maximizing production efficiency, reducing waste, and ensuring the highest quality end products.

Our team conducts an in-depth, engineering-focused analysis of each product, identifying potential design improvements that could enhance product functionality.

By thoroughly examining every aspect of the design, our engineers can recommend adjustments that contribute to a more streamlined production process and a higher quality end product.

Choose the Right Silicone Material

Silicone Material: To make the best decision, communicate your specific application requirements to our team, and we will recommend the ideal material for your unique use case.

Silicone Material Classification and Properties: Silicone materials can be broadly classified based on their physical, chemical, and mechanical properties.

Some common categories include:

  • High consistency rubber (HCR)
  • Liquid silicone rubber (LSR)
  • Fluorosilicone rubber (FSR)

Each type has distinct characteristics and is best suited for specific applications, making it crucial to consider factors such as temperature resistance, flexibility, hardness, and chemical compatibility when selecting the appropriate material.

Color Matching in Product Design

Color Matching in Product Design: As the first aspect that catches the eye, it is essential to give careful consideration to color matching during the product design process to ensure a visually appealing product that resonates with your target audience.

Our Color Matching Services: We offer a variety of color matching services to help you achieve the desired hue for your silicone part. Our color matching options include:

  • Pantone Match: Choose a color from the Pantone Formula Guide (Solid Coated) book or Electronic Pantone online. Ensure the selected color number ends with the letter ‘C’ to achieve accurate color reproduction in the final product.
  • Physical Match: If you have a physical item with the desired color, our expert color specialists can create a custom pigment and color formula that closely matches your sample. Simply send us the color sample, and we will develop a formula that achieves a 99% match with your reference item.


One of the crucial factors in designing custom silicone parts is cost. Throughout the new product design phase, we focus on various aspects that impact cost, ensuring that the final product meets the clients’ expectations without compromising their budget.

At the beginning of the design process, our engineers engage in open discussions with clients to understand their target price and annual expected part volume. This information allows us to make informed decisions during the design process and select cost-effective solutions tailored to the clients’ specific requirements.

Several factors influence the cost of custom silicone parts, including their size, weight, and complexity. Our engineering team carefully considers these factors during the design process, optimizing each aspect to strike a balance between cost and performance.

To provide clients with high-quality custom silicone parts that fit within their budget, our also offer recommendations in various areas, such as Material Selection, Structural Analysis, Mold Cavitation, Surface Finish, Branding Methods.
