Don’t just look at the scale! Identify the authenticity of a silicone rubber factory’s technical strength from these 4 points

Looking for a silicone rubber factory to cooperate with? Just hearing claims like “ten years of experience” or “annual output of 10,000 tons” is not enough. Technical strength is the core of reliable products. In fact, you can see through it from 4 details. When purchasers and enterprises choose a factory, following these details can help avoid 90% of the pitfalls! First, check if the R&D team is strong. A truly capable factory will have dedicated formula R&D engineers who can adjust hardness and temperature resistance according to working conditions. For example, when making seals for new energy vehicles, they can increase the temperature resistance of silicone rubber to 250°C without deformation. Those who can’t even explain “Shore hardness” are probably not reliable in terms of technology.

Then, check how sophisticated the production equipment is. Reliable manufacturers use fully automatic vulcanizing machines and laser thickness gauges, which can control production errors within 0.02mm, resulting in silicone products with smooth edges and no burrs. Small workshops use old equipment, leading to products that are either inaccurately sized or unevenly vulcanized, which crack when used.

Testing capabilities are also crucial. Regular factories have a complete set of testing equipment to measure the aging resistance and chemical resistance of silicone, and each batch of goods is accompanied by a test report. Those without testing capabilities rely entirely on “visual inspection,” resulting in low product compliance rates and prone to quality disputes in the later stage.

Check if the customized cases are authentic. Those that can handle high-demand orders in medical, aerospace, and other fields must have qualified technologies. For example, when manufacturing components for surgical instruments, they can achieve non-toxic, odorless, and disinfection-resistant properties. Those that only produce general-purpose products and dare not take on complex customization orders are mostly of average technical level.

5 Practical Tips to Help You Quickly Identify the Authenticity of Food-Grade Soft Silicone

Whether you are buying baking molds, baby teething toys, or kitchen scrapers, everyone looks for “food-grade soft silicone“. However, the market is mixed with good and bad products, and it is easy to buy inferior ones! In fact, it is not difficult to distinguish. With these 5 practical tips, ordinary people can easily do it.

First, check the certification marks! Regular food-grade soft silicone must be labeled “for food contact” and must meet the domestic standard GB4806.11. Exported products should have FDA certification. Those that only claim to be “food-grade” but cannot provide test reports are probably made of recycled materials, so you can directly pass them by.

Then, smell the odor to distinguish good from bad! Real soft silicone basically has no peculiar smell when opened, at most a faint smell of silicone itself, which will dissipate after a few minutes of ventilation. Inferior products will emit a pungent chemical smell or plastic smell, which is due to the addition of harmful additives. Long-term contact with food is extremely dangerous.

Hands-on testing is very useful! Those that can rebound quickly and not deform after stretching are reliable. Inferior ones will become loose or even break when stretched. You can also boil them in boiling water for 5 minutes. Genuine products will not turn yellow, fade, or have peculiar smells after boiling, while fake ones will deform, crumble, and release harmful substances.

Choosing the right merchant is crucial! Prioritize brands or suppliers with a good reputation that can provide inspection reports. Don’t trust products from “three-no” small workshops. For bulk purchases, you should verify the production process to avoid pitfalls.

Don’t be greedy for low prices! High-quality silicone raw materials and high production standards mean the price will not be particularly low. Products that are too cheap are either fake or shoddy. It may seem like saving money, but it actually harms your health.

Whether you are an individual buying household soft silicone products or an enterprise customizing food-contact soft silicone products in bulk, are you worried about buying non-food-grade ones? Click on the online customer service. We provide soft silicone products that meet GB4806.11 and FDA certifications, support inspection report inquiries, and help you choose with confidence!

Silicone products manufacturers
Silicone products are beautiful, because you can spray a variety of patterns on the surface, but many silicone product manufacturers in the spray, the pattern ink is easy to fall off, what is the reason? This article will explain some points that need to be paid attention to when spraying.

First, use special silicone spray ink

This is very important, if you take plastic spray ink to spray, it will definitely fall off, because different materials corresponding to the ink is not the same. Many customers encounter this problem, they can not find a professional silicone product manufacturer, may be the plastic factory packaging silicone products, plastic factory directly with inkjet spray onto the silicone products, the spray method is the same, but because the material is different, the effect is completely different.

Second, the surface of the product must be cleaned before spraying

It is necessary to dispose of the dust impurities on the surface, etc. If the PU is sprayed, the surface should also be treated with flame or discharge to ensure the ink fastness. If not cleaned, the effect of spraying on the surface will be poor.

Third, the surface of the product directly spray dyeing ink

To make the spray pattern more firm, transparent color sensitive oil, light oil, PU oil, etc. will be sprayed on the surface, so that the color will not fade easily, and there will be no color oil.

Silicone product injection process seems simple, but the above points deserve special attention. It is also important to choose the manufacturer of silicone products,

The difference between liquid silicone and solid silicone

Liquid silicone is a kind of flexible thermosetting material, non-toxic, heat resistant, high resilience. Compared with solid high temperature vulcanized silicone rubber, it is a liquid silicone with good fluidity, fast vulcanization, safer and more environmentally friendly, and can fully meet food grade requirements. In addition, liquid silicone products are soft and hardness can reach 10°C-40°C. Due to its soft properties, it is widely used in the simulation of human organs and medical silicone breast pads.

LSR is a two-liquid rapid vulcanization material with platinum as catalyst, which can be produced by injection molding, mass, rapid vulcanization, and repeated machinery. Its products have good thermal stability, cold resistance, excellent electrical insulation properties, and will not produce toxic substances when burning. However, due to the high expansion coefficient of LSR, it expands when heated and shrinks slightly when cooled. As a result, parts cannot maintain precise side spacing in the mold.

In addition, the cured LSR is easy to stick to the metal surface, the more common release technology includes thimble and air push, liquid silicone is divided into A glue and B glue, the use of quantitative devices to control the ratio of 1:1, injection injection molding production, liquid silicone into the hot channel mold, manufacturing silicone products, can be formed without waste and automation.
