In our daily life, silicone rubber products are everywhere, from kitchenware to medical equipment, from electronic products to auto parts. They provide convenience for our life and work with their outstanding performance. But do you know that behind these seemingly ordinary silicone rubber products lies a complex and meticulous customization process? Today, let's step into a silicone rubber products factory together and unveil the mystery of the customization process.
1、Demand communication and evaluation
All customization processes begin with communication with the client. Our professional team will have in-depth communication with customers to understand their specific needs for silicone rubber products, including the application, function, size, color, performance requirements, etc. of the products. During this process, we will inquire in detail about the customer's product application scenarios, such as whether it is for food contact utensils, industrial components that require high-temperature resistance, or medical supplies with special requirements for softness, so as to determine the appropriate silicone rubber material and formula.
Meanwhile, we will also assess the complexity and production difficulty of the product. If the customized products required by the customer have unique shapes, complex structures, or special surface treatment requirements, we will inform the customer in advance of the possible production challenges and cost increases they may face. Through this stage of communication and evaluation, we can provide customers with an initial customized plan and quotation to ensure that both parties reach an agreement on the expectations of the customized products.
2. Design and Modeling
After the customization requirements are determined, designers will use professional design software to carry out product design based on the product concepts and functional requirements provided by the clients. During this process, they will comprehensively consider factors such as the physical properties of silicone rubber, molding techniques, and the final usage environment of the product to ensure that the designed product is both aesthetically pleasing and practical, while also being able to proceed smoothly with production and manufacturing.
After the design is completed, we will produce a three-dimensional model of the product. This model can not only visually display the appearance and structure of the product, but also predict the performance of the product in actual use through simulation analysis, such as whether there are stress concentration points and whether it is prone to deformation. If any unreasonable aspects are found in the design, we will make timely adjustments and optimizations until the model reaches its best state. The design and modeling work at this stage is the key to the entire customization process, as it determines the basic form and performance basis of the product.
3. Material selection and formula adjustment
Silicone rubber is a material with a variety of excellent properties, such as good temperature resistance, chemical corrosion resistance, and electrical insulation. However, different types of silicone rubber also vary in performance, so choosing the appropriate silicone rubber material is of vital importance. We will select the most suitable material from a wide variety of silicone rubber types based on the performance requirements of the customers for the products. For example, for products that need to come into direct contact with food, we will choose silicone rubber that meets food-grade standards; For products that operate in high-temperature environments, silicone rubber with excellent high-temperature resistance will be selected.
In addition to choosing the appropriate materials, we will also adjust the formula of silicone rubber. By adding different additives, the performance of silicone rubber can be improved, such as enhancing its strength, improving its flexibility, and increasing its flame retardancy. During this process, our technicians will conduct a large number of experiments and tests to ensure that the adjusted formula can meet the performance requirements of the product. The accuracy of material selection and formula adjustment is directly related to the quality and performance of the product and is an indispensable part of our customization process.
4. Mold making
Molds are the key tools for the molding of silicone rubber products, and their quality directly affects the appearance and dimensional accuracy of the products. During the mold-making stage, we will conduct precise mold design based on the three-dimensional model of the product. After the design is completed, high-precision processing equipment will be used for mold manufacturing. During the manufacturing process, we will strictly control the dimensional accuracy and surface roughness of the mold to ensure that the mold can meet the forming requirements of the product.
For some products with complex shapes, it may be necessary to adopt multi-cavity molds or special mold structures to achieve them. After the mold is made, we will also conduct strict inspections and adjustments to ensure that all parts of the mold can work normally and that the formed products meet the design requirements. The cycle and cost of mold making depend to a certain extent on the complexity and precision requirements of the product. However, we will do our utmost to shorten the mold making cycle and reduce the customer's cost while ensuring quality.
5. Production and molding
When all the preparatory work is completed, it enters the production and shaping stage. We put the silicone rubber raw materials that have been adjusted in the formula into the molding equipment. Through processes such as heating and pressurization, the silicone rubber is formed in the mold. During the molding process, we need to strictly control parameters such as molding temperature, pressure and time to ensure the molding quality of the product. Different silicone rubber materials and product shapes have different requirements for molding parameters. This requires our operators to have rich experience and professional skills, and be able to flexibly adjust the parameters according to the actual situation.
The formed silicone rubber products will undergo cooling and demolding treatment. During the demolding process, we need to be careful to avoid causing damage to the product and ensure its intact appearance. Then, a preliminary appearance inspection of the product will be conducted to eliminate those with obvious defects, such as bubbles on the surface or dimensions that do not meet the requirements. The production and molding stage is the core link in the customization process of silicone rubber products. The quality and output of the products both depend on the operation level and equipment performance at this stage.
6. Post-treatment and quality inspection
Freshly formed silicone rubber products may still have some problems, such as rough surfaces and many burrs, which requires post-treatment. Post-processing mainly includes procedures such as trimming, grinding and cleaning of the product. Through these processes, the appearance of the product can be made smoother and neater, and the sense of quality of the product can be enhanced.
After the post-processing is completed, we will conduct a comprehensive quality inspection of the products. The contents of quality inspection include the appearance dimensions and performance indicators of the products, etc. Appearance and size inspection mainly checks whether the dimensions of the product meet the design requirements and whether there are any defects on the surface, etc. Performance index testing is to verify whether the product meets the customer's performance requirements through a series of experiments, such as temperature resistance tests, tensile strength tests, insulation performance tests, etc. Only after undergoing strict quality inspection can qualified products enter the packaging and shipping process.
7. Packaging and Shipping
The last step is the packaging and shipment of the products. We will select appropriate packaging materials and methods based on the customer's requirements and the characteristics of the products. For some fragile products, we will use cushioning packaging materials for protection. For products that require moisture-proofing, we will use moisture-proof packaging. After the packaging is completed, we will count and verify the products to ensure the accuracy of the shipment quantity.
Then, we will select reliable logistics partners to deliver the products safely and on time to customers. Throughout the entire packaging and shipping process, we pay close attention to details to ensure that the products are not damaged during transportation, allowing customers to receive satisfactory products on time.
