Key Points to Know When Sourcing Spray Pumps
Key Points to Know When Sourcing Spray Pumps
As a professional fine mist sprayer manufacturer, we have deeply engaged in the production of spray pumps and supporting spray bottles, providing a full range of spray packaging solutions for the beauty and personal care industry. We also support flexible procurement models including fine mist spray bottle wholesale, fine mist spray bottle bulk, mist spray bottles bulk and wholesale mist spray bottles. Nowadays, spray products such as women's perfume, air fresheners, and beauty & skincare mists are being widely used. The spraying effect directly determines the consumer experience, and spray pumps, as the core supporting components of such products, play a crucial role. This article will detail the core basic knowledge of spray pumps as packaging consumables for buyers, providing professional references for procurement decisions.
Product Definition
A spray pump, also known as a spray head, is a core accessory for beauty and skincare containers and an important type of quantitative dispenser. It operates on the principle of atmospheric equilibrium, expelling the contents from the bottle through pressure. When liquid flows out at a high speed from the nozzle, it drives the surrounding gas to flow faster and the pressure to drop, forming a local negative pressure. This further makes the surrounding air fully mix with the liquid to form an aerosol, achieving atomized spraying of the liquid—this is the core technical key of high-quality fine mist spray pumps.
Manufacturing Process
1. Moulding Process
Spray pumps are mainly designed in snap-fit (half bayonet/full bayonet) and screw-thread structures, with plastic as the main material. Some high-end models are paired with aluminum outer covers or electroplated aluminum technology to enhance the texture. The core internal components of spray pumps are all made of food-grade and beauty-grade plastic raw materials such as PE, PP and LDPE through injection moulding. Auxiliary parts such as glass beads and springs are custom outsourced to ensure product precision and operational stability.
2. Surface Treatment
Components can be processed with vacuum metallization, aluminum electroplating, painting or color injection to meet the customized appearance needs of different brands and adapt to the visual design styles of various beauty packaging.
3. Graphic Processing
Patterns can be printed on the nozzle and collar surfaces of the spray pump via hot stamping or screen printing. However, nozzles are usually left unprinted for the sake of simplicity in production and use.
Product Composition
1. Main Accessories
A common spray pump consists of a push nozzle/head, diffuser, central dip tube, locking cap, sealing gasket, piston core, piston, spring, pump body, suction tube and other components. During operation, the piston is connected to the valve seat to open or close the pump body. Although the accessory details of spray pumps vary with different designs, the core function of all accessories is to ensure efficient, quantitative and atomized liquid discharge of the contents. This is the core reason why we, as a professional fine mist sprayer manufacturer, strictly control the precision of every accessory in production.
2. Liquid Discharge Principle
The liquid discharge process of a spray pump is divided into three core stages, which work together to ensure the stability of liquid discharge and atomization effect:
- Exhaust Process: Initially, there is no liquid in the chamber. Pressing the head compresses the spring, pushing the piston and valve seat down, increasing the air pressure until the gas escapes.
- Suction Process: Releasing the head decompresses the spring, closing the gap between the valve seat and the piston, thus creating a vacuum that draws liquid into the pump.
- Discharge Process: Similar to the exhaust process, but the chamber is already filled with liquid; pressing the head forces the liquid out.
Atomization Principle
The small nozzle accelerates the liquid ejection, forming a high-speed airflow that impacts the liquid droplets and refines them. The high-speed liquid flow also drives the flow of surrounding gas, reducing the local pressure and mixing air with the liquid to produce an atomization effect.
Industry Applications
As a core packaging accessory for the beauty and personal care industry, spray pumps are widely used in various products such as perfume, gel water, air fresheners, skincare essence mists, and moisturizing mists, serving as the key component of spray-type beauty packaging. Our supporting spray bottle products including fine mist spray bottle wholesale and mist spray bottles bulk can be precisely matched with spray pumps of different specifications to realize integrated procurement of packaging.
Procurement Precautions
- Dispensers of spray pumps are mainly divided into zigzag and screw types; the suitable type should be selected according to the product packaging design.
- Select a spray pump that is precisely matched with the bottle caliber, and customization is available according to customer needs.
- The mould development of spray pumps involves a wide range of categories and high mould opening costs. As a professional fine mist sprayer manufacturer, we have a large number of mature moulds to meet customers' spot procurement needs, and also support customized mould opening. We provide cost-effective solutions for customers with bulk procurement needs such as fine mist spray bottle bulk and wholesale mist spray bottles.
