How to ensure details in customized silicone parts? Silicone parts are quietly integrated into daily scenarios such as medical devices, household small items, electronic devices, etc. due to their flexible touch, temperature resistance, and chemical stability. When standard components are difficult to fit unique structures or functions, customization becomes a natural choice. However, from a requirement description to the final product in hand, material selection, process refinement, and detail confirmation are interrelated. A slight negligence may affect the fit and service life of the parts. The starting point of customization is to clearly 'translate' the requirements into technical language. When communicating with suppliers, it is necessary to clarify the usage environment: whether it comes into contact with humans or food? How much pressure can you bear? What is the working temperature range? For example, baking molds need to withstand high temperatures of 230 ℃, while therapy equipment handles focus on softness and slip resistance. Attaching a diagram or physical reference can significantly reduce misunderstandings and pave the way for subsequent steps.Material selection is like "qualitative" analysis of a component. Silicone hardness is indicated by Shore A, and can be adjusted as needed, ranging from jelly like softness to slightly elastic solidity. Colors are not limited to basic colors, but can also be customized with textures such as matte and semi transparent. If there are special requirements involved, such as medical grade biocompatibility or food contact certification, they must be explained in advance. The supplier will provide samples of the corresponding materials for touch and confirmation, and it is safe to see them by hand.Design and molds are the soul of customization. Engineers will optimize the details of the drawings: adjust the demolding angle, ensure uniform wall thickness, and avoid shrinkage or burrs during production. The precision of the mold directly determines whether the contour of the part is smooth. The samples produced during the trial stage need to be personally inspected to ensure their size is accurate? Is the edge rounded? Is the assembly smooth? The patient confirmation in this step can effectively avoid regrets after mass production.The production process emphasizes the importance of heat and moderation. Liquid silicone injection is suitable for precision small parts, while solid-state molding is used for slightly larger structural parts. Temperature, pressure, and vulcanization time need to be strictly controlled. Quality control runs through the entire process: randomly check the size, carefully inspect the surface for bubbles, impurities, or color differences. The finished product is individually packaged after gentle cleaning, especially in areas with high cleanliness requirements, where every step shows respect for details.Occasional minor situations can also serve as opportunities for communication. If the edges of the sample are slightly rough, it may be due to mold trimming or fine-tuning of process parameters; Color deviation requires checking the color card and sampling records. Honest communication and joint analysis often lead to quick solutions. Choosing a partner who is patient in communication and has solid experience will make the customization process smoother and more secure.

ご存知の通り、シリコーンは、耐熱性、耐寒性、化学的安定性に優れた特性を持つことから、キッチン・家庭用品、電子機器、自動車などの分野で好んで使用される素材となっています。その鍵は、高い耐熱性能にあります。 シリコーンの耐熱性は、ポリジメチルシロキサンのユニークな分子構造に由来します。主鎖のSi-O-Si結合エネルギーは、一般的なゴムのC-C結合エネルギーよりもはるかに高く、熱安定性は非常に優れています。また、分子鎖には柔軟性があり、有機側基との結合によって保護効果を生み出し、高温環境下での分解や変形を困難にし、長期間にわたって良好な弾性を維持することができます。耐熱性の観点から、シリコーンは複数のグレードに分類できます。一般的なシリコーンは、-60℃から200℃の温度範囲で長期間使用でき、短期的には250℃までの高温に耐えることができます。改良された耐熱シリコーンは、キッチン用品や一般的なシールなどの一般的なシナリオのニーズを満たすことができます。その長期耐熱性は200℃から250℃に向上し、短期的には300℃に達することができます。自動車エンジンや高温蒸気装置などの産業用途に適しています。特殊耐熱シリコーンは、ベンゼン、フルオロシリコーンで改良したり、セラミックを充填したりすることができます。その長期耐熱性は250℃から300℃に達し、短期間のピークは350℃を超えることもあります。航空宇宙や消防設備などの極端な高温条件に対応できます。さらに、シリコーンの実際の耐熱性は、原料の純度、製造プロセス、使用環境によっても影響を受けます。高品質のシリコーンは、二次加硫プロセスによって耐熱安定性をさらに向上させ、高温での変形や臭いの問題を軽減できることは注目に値します。

Staining is a common problem with silicone products, and we often encounter situations where the surface of silicone products is very dusty. So, how should we deal with this situation? The phenomenon of sticking to dust and debris is due to the inherent chemical properties of silica, and the phenomenon of adsorption force is an inevitable factor in raw materials. Therefore, for silicone products used in daily life and placed in textiles, plush, etc., adhesion will definitely occur. However, for such phenomena, they need to be processed and solved by silicone product manufacturers. It should be noted that adsorption force is the main reason for the accumulation of dust powder in silicone products. Therefore, the additives in organic silicon and inorganic silicon are different in the raw materials. Different adsorption methods can reduce the silicon chain structure units in silicone materials. Adding a large amount of water during raw material mixing can destroy the adsorption strength of silicon hydroxyl groups and reduce the active proportion in silicone adsorption. After molding, silicone products belong to the untreated process, so the surface will have the ability to automatically adsorb dust. However, static electricity can be covered by electrostatic oil surface spraying to prevent adsorption ability. There are two methods of treatment. Before processing and production by silicone product manufacturers, anti-static glue is used to control the adsorption energy and anodization of silicone in the raw materials. Another method is to spray oil on the generated silicone product surface to achieve a smooth and anti-static effect.
