The Best Way To Produce Silicone Products

Introduction

The silicone products industry is booming right now, with loads of different sectors like maternal and infant care, medical industry, electronics industry, auto parts, labor protection insurance, kitchen and bathroom， cable accessories and so on.

If you're a silicone product manufacturer, staying ahead means mastering the most efficient and innovative production methods.This blog looks at the best ways to produce silicone products, making sure they're top quality, cost-effective, and easy to scale up for your business.

Why Silicone? The Material of the Future

Silicone is a super versatile material. It's really durable, flexible and resistant to extreme temperatures. Whether you're making medical devices, kitchenware or industrial components, silicone is the best.

But how to make silicone products that stand out in a competitive market? It all starts with the right production process.

What Are The Best Ways To Manufacture The Silicone Products？

Production enterprises in the production process, improve product yield and increase production capacity is the key to the product. Liquid silicone products in the production of what common phenomena will be encountered, and how do we solve or avoid it?

Liquid silicone products by silicone product manufacturer in the production of common defects are trapped air, glue is not full, burrs, poor size, product sticking and other phenomena.

Difficulties in the production of products

1. The temperature is too low
2. Vulcanization time is too short
3. Non 1:1 into the rubber
4. System or pipeline contamination

1. Temperature Too Low

Ideal Vulcanization Temperature: For Liquid Silicone Rubber (LSR), the optimal temperature range is typically 160°C to 200°C.

2. Vulcanization Time Too Short

Optimal Vulcanization Time: Depending on the product thickness and mold design, vulcanization time typically ranges from 10 seconds to several minutes.

3. Non 1:1 Mixing Ratio

Importance of 1:1 Mixing: LSR typically requires a 1:1 ratio of base rubber to catalyst for proper curing.

4. System or Pipeline Contamination

Impact of Contamination:

Contamination can reduce vulcanization efficiency by up to 50%, leading to surface stickiness and weak structural integrity.

Studies show that even 0.1% contamination can cause a 15-20% drop in product performance.

For some thicker liquid silicone products, vulcanization time is not enough, or vulcanization is not enough, it is easy to appear sticky phenomenon.

So pay special attention to the adjustment of process parameters.

At the same time, for the above reason analysis, we can from the following aspects to solve the problem of liquid silicone products sticky:

1. Check whether the actual mold temperature is consistent with the setting, such as consistent with the appropriate temperature.
2. Extend the vulcanization time.
3. Adjust the feed pressure, check the feed slow component of the one-way check valve is normal or in a normally open state.
4. Check whether the solvent used for cleaning contains polymerization blocking ingredients. 

Liquid Silicone Solution for Maternal and Infant Products

Liquid silicone material due to its excellent environmental protection and safety, making its application more and more widely.

Especially maternal and infant class we common liquid silicone products are: pacifiers, milk bottles, spoons, plastic bowls, teethers, breast pumps and so on. In the production of these products, some silicone product manufacturer have mentioned that the product has bubbles or white spots of the phenomenon, which has an impact on the appearance of the product.

So how do we avoid these problems in production?

The maternal and infant liquid silicone products are generally required to be highly transparent, clean products without defects.

The main reason for the appearance of bubbles or white spots is that the gas is not discharged in time, trapped in the product.

Analyze the reasons are as follows:

1. The temperature is too high, the vulcanization time is too short, in too high a temperature or too short a time to vulcanize, the gas in the product is too late to discharge.
2. The injection speed is too fast.
3. The viscosity of the rubber is too low. 

Secondly, for some relatively thin liquid silicone products, it is also easy to produce bubbles or trapped gas. So in the mold design time need to pay special attention to the design of the runner and glue mouth.

The methods to solve the air bubbles of maternal and infant liquid silicone products are as follows:

1. Reduce the mold temperature. Appropriate high temperature can shorten the product molding time, but it is not the higher the temperature the better. This needs to be adjusted in the actual trial molding process to find a temperature and molding time balance.
2. Adjust to reduce the injection speed.
3. You can adjust the material, find the rubber viscosity higher material, or reduce the vulcanization speed. 

Conclusion| Mastering the Art of Silicone Production

Whether you're exploring how to make silicone products or scaling your manufacturing process, the key lies in choosing the right method and partner. From LSR molding to 3D printing, each technique offers unique advantages tailored to specific needs. By staying informed and leveraging industry best practices, you can position your business as a leader in the silicone products market.
