Glass Bottle Manufacturing Process

Ruisen glass bottle manufacturer

Yuncheng Ruisen Glass Co., Ltd. is a company specializing in the glass bottle manufacturing. We always adhere to the business philosophy of “quality creates quality products.” We carefully consider all the details in every step of glass bottle manufacturing process. And we guarantee that each product complies with relevant national standards and requirements.

High-quality glass bottles of Ruisen

High-quality glass bottles of Ruisen

The company developed crystal white glass bottles through research on glass. This material has higher permeability, uniform glass thickness, and market acceptance. Through the flexible pressing of the feeder, we can produce glass wine bottles from 50 to 3000 ml. We bought a big new machine to make glass bottles that look good and have even lines inside. The bottle is almost perfect and made of eco-friendly, lead-free glass.

The company can use customers’ products or drawings to do 3D printing quickly. We studied the product and found that the company is fast, accurate, and ruthless. This saves time and increases efficiency. You can easily see what the product looks like and talk to the technical department to study it.

We make molds for glass bottles, like forming molds and prototype molds. We also make molds for the bottle mouth, funnels, bulkheads, bottom, punches, and cores. There are different types of glass bottle machines: row machine (automatic), 8S (automatic), 9s (automatic), 6S (manual manual clamping).

Main products of Ruisen

Our main products are super flint and high flint glass bottles:

Super Flint and High Flint are vital for making glass bottles. Using them makes bottles firmer, more transparent, and better able to withstand heat. You can choose between super or high flint based on what you need.

1. Super Flint is a crystal white glass bottle. It has a lot of silica (SiO2). Super flint costs more than high flint due to its purity and better properties. It has extremely high transparency, excellent heat resistance, and mechanical strength. It is often used to make fancy glass bottles like wine or cosmetics. These bottles need to be very clear and strong.

2. High Flint (High Flint): High Flint is a type of flint containing a high silica (SiO2) content. High flint is often used to make food and drink bottles because it is transparent and heat resistant. It is more cost-effective than super flint and is suitable for creating a wide range of products.

So, when deciding on the type of flint to use, consider product positioning, needs, and budget. Super Flint may be a better choice if you want a high-quality, transparent, and heat-resistant product. High flint can be a cheaper choice if your product requirements are more relaxed.

Whole glass bottle manufacturing process

Material selection

Material selection is the first step of glass bottle manufacturing. To extend the bottle’s shape, choose the right materials for making it. Ruisen Glass Co., Ltd. has a professional purchasing team that screens and tests materials strictly. When choosing materials, ensure they are pure and have the right composition. This ensures they meet standards for glass bottles making. We test materials regularly to make sure they are of good quality. The marerials: Quartz sand, sodium carbonate, and limestone make glass bottles.

Quartz sand

Quartz sand makes up over 70% of glass bottle weight, so it’s the main component. It is a mineral with high hardness. Its main component is silica. It can make glass bottles because it can handle high temperatures and is chemically stable.

Sodium carbonate

Sodium carbonate is a flux in glass bottles, which lowers the melting point of glass and makes it easier to melt. This material can make glass bottles stronger and more durable. It also increases transparency and hardness.


Limestone is a stabilizer for glass bottles. It can stabilize glass during use and stop it from changing color or deteriorating. Limestone can make glass bottles stronger and more resistant to wear and tear.

Three primary raw materials are used to make glass bottles, but some auxiliary materials are also required. These extra materials, like alumina and sodium oxide, improve the glass’s properties. This makes the bottles more transparent, stronger, and longer-lasting.

We use quartz sand, sodium carbonate, limestone, soda ash, and other stuff to make glass bottles. We heat the raw materials at high temperatures. Then, we shape and cool them to create glass bottles we use daily. When using it, we should protect the glass bottle to avoid hitting or dropping it so it lasts longer.



When the raw materials are ready, the next important step, called smelting, begins. To start, mix the raw materials in the right proportion. Then, put them in a hot furnace to melt. The furnace temperature goes above 1500°C and quickly melts the raw materials. This creates a big amount of molten glass due to the high temperature and pressure. After smelting, the liquid glass must be uniform and impurities-free.
Mold forming

To make glass fiber, pull out the melted glass liquid. It goes through cooling, shearing, symmetry processing, and other processes. Finally, it enters the mold-forming process. To make bottles of various shapes, we need different molds. You must adjust and fine-tune each mold to meet bottle strength, shape, size, and beauty requirements.

Annealing and inspection

Annealing and inspection

After forming the bottles, the workers anneal them to strengthen them and remove stress. Once the annealing process is complete, we must inspect the bottles for quality. During inspection, we check how the glass bottles look, size, shape, weight, etc. If we find any that are defective or not up to standard, we don’t throw them in the waste. Once the quality inspection department approves the bottle, it can proceed to the next step.

Printing and assembly

We print the company logo and details on the surface to make the bottle look nice. We put the checked glass bottles in packages to keep them safe for transport and sale. The packaging method is usually box packaging or pallet packaging. We choose packaging materials that meet hygiene standards for product safety and quality.

Glass bottle color spraying process

Of course, customers’ needs can also determine the color of the bottles. Glass bottles are usually colored in several steps.

1. Cleaning: Clean the glass bottle to remove oil and impurities on the surface. This will make the surface smooth.

2. Spray primer: To ensure the adhesion and color effect of the coating, you need to spray primer first. Using a primer on glass bottles can make them smoother and protect them from oxygen damage.

3. Spray color: Put the glass bottle under the spray equipment to spray color. Then, use compressed air to spray paint evenly on the glass bottle’s surface. You should prepare the selection of pigments according to actual needs.

4. Drying: We place the glass bottles in a drying room to dry naturally or with heat after spraying. Drying time depends on factors such as the type of pigment and ambient temperature.

5. Packaging: After inspection, we can package, label, etc., the dried glass bottles.

To make sure the color is accurate and the coating is firm, dust the equipment and environment while spraying. We must treat the surface to prevent static electricity problems while spraying.
Custom glass bottle

Ruisen offer more than just decorating glass bottles. We can provide custom glass bottles. We can also provide related products and services, including outer packaging boxes, cloth bags, and custom cartons. Our company have wine bottle caps in different styles and materials. We can also make custom cap shapes based on customer preferences. The materials for glass bottle lids include glass, wood, and plastic. These materials work well for liquor glass bottles. Become our partner, and you will enjoy a one-stop service.
