What are the steps in the main production process of glass lotion pump bottle?
Raw material preparation and glass bottle manufacturing
Glass lotion bottles are usually made of high borosilicate or soda-lime glass materials and are formed by heat processing of molds. The production process of glass bottles includes:
Mixing and melting: Mix quartz sand, soda ash, limestone and other raw materials in proportion, and melt them in a furnace at a high temperature of more than 1400℃ to form glass liquid;
Molding: Form the required bottle shape through a blow mold process or a press mold process;
Annealing: Place the bottle body in an annealing furnace and gradually cool it down to eliminate internal stress and improve structural strength;
Quality inspection: Use automatic detection equipment or manual inspection to eliminate defective bottles such as bubbles and cracks.
Bottle surface treatment and decoration
In order to enhance brand recognition and visual beauty, glass bottles often require a variety of surface processing processes. Shaoxing Roman Plastic Co., Ltd. has a professional spraying and printing workshop, which can provide the following processing services:
Spraying and UV coating: to achieve visual effects such as frosting, pearlescent, transparent, and metallic;
Screen printing and thermal transfer: used for printing brand logos, text descriptions and patterns;
Hot stamping/hot stamping: to increase the sense of luxury and texture expression;
Labeling processing: suitable for the pasting of composite materials or multi-language labels.
We have more than 50 injection molding equipment and 15 assembly and packaging production lines, which can flexibly undertake large-scale and personalized customization projects, including OEM and ODM services.
Pump head injection molding and metal spring assembly
The manufacturing of the pump head mainly uses plastic materials such as ABS and PP, which are molded in one time by high-precision injection molding equipment. The internal structure of the pump body, such as the piston, seal ring and spring, requires high-precision assembly:
Injection molding production: Our company's injection molding equipment completes the production of multiple components such as bottle caps, press heads, pump cores, etc.;
Metal spring assembly: used to control the rebound force of the liquid output, which requires precise positioning;
Air tightness test: ensure that the pump head has no leakage and no penetration when combined with the glass bottle body;
Liquid output detection: generally controlled between 0.2-0.5ml, and the dosage size can be adjusted according to customer needs.
Assembly of pump head and glass bottle
This step is the key stage for the entire lotion pump bottle product to move from semi-finished products to finished products:
Thread matching or snap-on docking: the pump head and the bottle mouth must match the standard caliber (such as 18/415, 24/410, etc.);
Add gasket seal: prevent liquid leakage and improve air tightness;
Assembly of screw cap or lock device: ensure compact structure and intact appearance;
Whole bottle sealing detection and appearance quality inspection: use vacuum testing equipment for final sealing inspection.
What are the advantages of glass lotion pump bottle in application?
Material advantages: natural purity, high stability
Compared with plastic, glass material has better chemical stability and barrier properties. When storing lotions, essences or skin creams containing active ingredients for a long time, it is not easy to react chemically with the contents. It is especially suitable for natural, organic, and highly active skin care product packaging.
In addition, glass bottles have good air tightness and anti-leakage properties, which can effectively prevent the volatilization, oxidation or deterioration of the contents, and provide strong guarantee for the shelf life of the product.
In the product series of Shaoxing Roman Plastic Co., Ltd., we use high-quality glass bottles and combine them with self-developed high-precision plastic pump heads to ensure that the sealing and durability of each lotion bottle during use meet international standards.
Appearance texture: high-end vision, shaping brand temperament
The glass lotion pump bottle, with its crystal clear and heavy texture, naturally carries a high-end and pure aesthetic atmosphere, which can quickly improve the product grade and brand awareness. In the market, glass packaging is widely used in high-end skin care lines such as anti-aging essences, luxury creams and customized beauty serums.
Shaoxing Roman Plastic Co., Ltd. has rich experience in bottle processing, equipped with advanced surface treatment equipment and professional teams. We can provide:
Multi-layer spraying and UV coating treatment to achieve visual effects such as matte, frosted, and metallic texture;
Silk screen printing, hot stamping, and thermal transfer technology to help shape the brand image;
Personalized labeling and packaging matching, providing customers with one-stop customized services.
With exquisite craftsmanship and rich aesthetic experience, we help customers transform product concepts from "visual language" into real products.
Usage experience: precise liquid discharge, clean and convenient
Compared with traditional bottle mouths, glass lotion pump bottles are equipped with pump head structures, making the product use process more convenient and hygienic. The pump head has the following advantages:
Precisely control the amount of liquid discharge, and the common dosage is controlled between 0.2ml-0.5ml, which is suitable for high-concentration skin care formulas;
Avoid secondary contamination: The pressing pump head design can reduce direct contact between hands and contents;
Leak-proof structure design: The bottle mouth sealing ring and the spiral bayonet structure can effectively prevent liquid leakage, and even ensure safety during transportation.
Shaoxing Roman Plastic Co., Ltd. has more than 50 injection molding machines, which can accurately manufacture pump heads of various specifications and structures, and support OEM/ODM pump body design to meet the personalized needs of different customers for dosage, bottle mouth size, and pump type.
Environmental attributes: strong recyclability, in line with the green trend
As the world pays more and more attention to sustainable development, environmentally friendly packaging has become an important direction for the development of the industry. Glass material, as a 100% recyclable material, has good sustainable properties and is suitable for brands to promote the "environmental protection concept" during the green transformation process.
Our company actively responds to the concept of green production and fully considers environmental factors in product design and process. For example:
Use environmentally friendly inks and UV coating materials;
Promote detachable structure design for easy classification and recycling;
Provide customers with sustainable packaging suggestions, such as simplified structure, alternative materials, green packaging design, etc.
