Professional Plastic Lotion Pump Supplier

ONE

Pump core definition and technical nature





Definition:

The pump core is the core of the Lotion Pump drive system, the mechanical structure of the pump core to generate negative / positive pressure, and realizes the liquid quantitative output and sealing preservation of precision components. Its performance directly determines the experience of using the product (e.g., precision of liquid dispensing, smoothness of pressing, sealing).

Technology Essence

Lotion pump supplier Micro-engineered Mechanical System: Integrated spring mechanics, fluid dynamics, tribology design in the space of 8-25mm in diameter.

Material Interface Science: Solve the compatibility contradiction between glass/metal/plastic/liquid (e.g. alcohol resistance, crystallization resistance)

Lifespan Reliability Engineering: Required to withstand ≥5000 times of pressing test (international standard ISO 22718)




Key Parameters:

- Dispensing volume accuracy: ±0.02g (e.g. 0.5g, 0.5g, 0.5g, 0.5g) 0.02g (e.g. 0.18g/pump) - Starting force: 30-60N (operable range for infants)

- Residue: ≤5% (EU EC 1223/2009 requirement)

TWO

Pump Cartridge Operating Principle

Pump Cartridge Operating Principle (4-stage cycle)



1.Downward stroke

- the presser head pushes the piston rod downward, the main spring is compressed

- the piston seal cuts off the passage between the liquid reservoir and the atmosphere

2.Vacuum formation

- the piston moves downward causing the pump chamber to increase in volume, internal air pressure < bottle air pressure

- the liquid in the bottle opens the bottom valve ball into the pump chamber

3.rebound discharge

- after release the main spring rebound to push the piston upward

- the bottom valve ball closed, the volume of the pump chamber decreases to form a positive pressure

- the liquid top open the piston valve from the nozzle injection

4.Reset Seal

- secondary spring pushes seal closed when piston is reset

- pump chamber is isolated from the outside world to prevent oxidation/volatilization



Precision Control Points:

- Tolerance of ball diameter ≤ 0.03mm (to control opening/closing sensitivity)

- Spring K-value deviation ± 5% (to ensure consistency of liquid discharge)

THREE

Procurement Core Control Elements





Mandatory Terms of the Technical Agreement

1. Compatibility Verification:

- 72h material immersion test (quality change rate ≤ 0.5%)

- Low temperature (-20℃)/high temperature (50℃) cyclic shock 3 times

2. Functional reliability:

I．Core Features of Plastic Bottles: Balancing Practicality and Flexibility



The widespread application of plastic bottles is closely tied to their outstanding characteristics. In terms of physical properties:Plastic bottles are lightweight and portable. With the same capacity, they are much lighter than glass bottles—this not only significantly reduces transportation costs but also makes them convenient for consumers to carry.Their shock-resistant (non-fragile) property prevents damage caused by collisions during handling, storage, and use, making them particularly suitable for scenarios that require frequent movement.

In terms of chemical properties, plastic bottles have excellent corrosion resistance. They can resist various chemical substances such as water, acids, and alkalis, effectively protecting products like personal care items, cosmetics, and cleaning agents from reacting with external substances and deteriorating.



II.Application Scenarios of Plastic Bottles: Meeting Needs Across Industries


With their diverse features, plastic bottles have an extremely wide range of application scenarios, penetrating into various fields of daily life and industrial production. In the food and beverage industry, PET plastic bottles are the absolute mainstay.

Plastic bottles with pumps can precisely control the dosage of products such as lotions, serums, and facial cleansers while preventing contamination—this type of lotion bottle with pump is highly favored by beauty brands. Additionally, small-capacity empty plastic bottles can be used for repackaging skincare samples, meeting consumers’ needs for product trials.





Plastic bottles boast good barrier properties and transparency, which ensure hygiene and product quality. Meanwhile, their lightweight feature makes them convenient for consumers to carry when going out.

In the pharmaceutical industry, plastic bottles—leveraging their excellent sealing performance and corrosion resistance—are used to hold pharmaceutical products such as oral liquids, capsules, and ointments. They effectively maintain the stability of pharmaceutical ingredients and prevent moisture absorption and deterioration.

Dear bosses in the daily chemical, personal care, and cosmetics industries, have you ever been troubled by "mismatched" packaging issues?​



Custom lotion pumps that don’t fit tightly with plastic bottles plastic bottle at the interface, leading to leakage during subsequent assembly; mini trigger sprays or mini trigger pumps with poor thread compatibility with bottle bodies, causing frequent loosening during use; PE bottles or HDPE bottles PE HD bottle whose materials are incompatible with product ingredients, resulting in deformation during storage — the root cause of these problems often lies in the disconnection between packaging design and product characteristics.​



As a lotion pump factory and plastic bottle supplier with 12 years of focus on packaging manufacturing, Guangdong Hongyuan is not only a reliable lotion pump supplier and lotion dispenser pump manufacturer , but also a one-stop source for plastic bottle supplies and various pump heads. We do not involve in finished product filling; instead, we focus solely on packaging itself. With in-depth mastery of the characteristics of PE plastic bottles , lotion pumps, spray pumps, and other packaging, we help you solve the pain point of "mismatch".



Why Do Factories Understand Packaging "Matching" Better? Because We Are Rooted in the Production Frontline and Master Every Detail​

Unlike pure design companies, Guangdong Hongyuan has full independent control over the entire process from raw material selection, mold development to the production of lotion pumps, HDPE bottles, and other packaging. We know well that high-quality packaging matching is never just about "matching sizes":​

For the "matching" of lotion pumps, we adjust the liquid output according to the viscosity of your products. As professional lotion dispenser pump manufacturers , we further optimize the pressing feel based on usage scenarios, and even select corrosion-resistant sealing rings according to the pH of ingredients to ensure no aging during long-term use;​

For the "matching" of plastic bottles , we select bottle materials based on your product’s storage needs — whether it’s PE bottles , HDPE bottles , or PE plastic bottles, we can provide accurate recommendations.

Meanwhile, we design the bottle mouth structure in line with subsequent assembly processes (manual capping vs. automatic pump installation), and ensure uniform bottle wall thickness to prevent damage during transportation. As a plastic bottle supplier and plastic bottle supplies service provider, we have a thorough understanding of the compatibility characteristics of various plastic bottles;​

For the "matching" of mini trigger sprays and mini trigger pumps , we balance the spray atomization effect and bottle capacity to ensure labor-saving pressing and precise spray range;​

The "matching" of overall packaging requires a more systematic approach — from the thread precision between lotion pumps and plastic bottles, to the assembly compatibility between mini trigger sprays and HDPE bottles , to the consistency between color matching, LOGO screen printing and your brand tone, and even the efficiency during mass assembly. Every detail relies on a dual understanding of packaging characteristics and your product needs.​

Whether it’s the combination of lotion pumps + HDPE bottles for daily chemical and personal care products, the matching of spray pumps + acrylic bottles for cosmetics, or the set of mini trigger sprays + PE plastic bottles for industrial cleaning, Guangdong Hongyuan, as a lotion pump factory and plastic bottle supplier , can leverage professional control to achieve high-quality design matching for the entire series of packaging. This ensures that the packaging you receive is easy to assemble and reliable to use.
