Leveraging its expertise in precision machinery and automation, Zhejiang Guoyu provides ‌high-precision, hygienic, and flexible production equipment and solutions‌ for the cosmetics and household chemicals industries. Its offerings span ‌personal care products (shampoos, body wash), cosmetics (creams, lotions), home cleaning agents (detergents, disinfectants), and aerosol products‌, empowering clients to achieve efficient production, quality control, and sustainable development. Below are its core applications and technological innovations in this sector:

‌1. Core Application Scenarios‌

‌a. Personal Care and Cosmetic Manufacturing‌

‌•‌High-Viscosity Product Filling‌:

- Servo-driven piston pumps and screw-filling technology for creams, lotions, and other viscous materials, with ‌±0.5% filling accuracy‌ and drip-free design to minimize material waste.

- CIP (Clean-in-Place) systems enable rapid switching between formulations (e.g., silicone-free or amino acid surfactant products).

‌‌•Aseptic Filling (Premium Skincare)‌:

- Cleanroom-grade filling lines (ISO Class 8) with laminar airflow protection and microbial monitoring, compliant with cosmetic GMP standards (ISO 22716).

‌b. Home Cleaning Product Production‌

‌‌•High-Speed Liquid Filling‌:

- Multi-channel parallel filling systems for 1L-20L detergents and disinfectants, achieving speeds of ‌200 bottles/minute‌ (500ml capacity).

- Corrosion-resistant materials (e.g., PTFE-coated pipelines) for handling strong acids/alkalis.

‌‌•Powder and Granule Packaging‌:

- Fully enclosed screw metering systems with residual dust <0.05g per cycle, suitable for laundry detergents, dishwasher salts, etc.

‌c. Aerosol Product Lines‌

‌‌•Precision Propellant Filling‌:

- Pressure-compensated filling technology for LPG, DME, and other propellants, with ‌±0.3% accuracy‌ and residual oxygen <0.5%.

‌‌•Leak Detection and Seal Integrity Testing‌:

- Laser sensors and AI vision systems automatically reject defective cans, reducing defect rates to ‌<0.01%‌.

‌2. Technological Advantages‌

‌a. Precision and Flexibility‌

‌‌•Multi-Format Compatibility‌:

- Modular designs allow rapid switching between bottle types, pouches, tubes, and other packaging formats (changeover time <15 minutes).

‌‌•Digital Control‌:

- PLC+SCADA systems monitor filling volume, pressure, temperature, and other parameters in real time, with traceability to batch/work orders.

‌b. Hygiene and Safety‌

‌‌•Sanitary Design‌:

- Equipment contact surfaces use 316L stainless steel or food-grade plastics, with rounded edges compliant with EHEDG standards.

‌‌•Cross-Contamination Prevention‌:

- Dedicated pipelines and color-coded connectors prevent residue mixing between formulations.

‌c. Energy Efficiency and Sustainability‌

‌‌•Resource Optimization‌:

- Heat recovery systems reduce steam consumption, while vacuum conveying minimizes material spillage.

‌‌•Eco-Friendly Packaging Support‌:

- Compatibility with recyclable bottles, concentrated refill packs, and other sustainable packaging solutions.

‌3. Client Case Studies‌

‌‌•An International Skincare Brand‌: Customized aseptic cream filling line with ±0.3% accuracy helped secure EU ECOCERT organic certification.

‌•‌A Leading Domestic Household Chemicals Company‌: 20L detergent production line boosted efficiency by 40%, saving over ‌RMB 2 million‌ annually in labor costs.

‌•‌Aerosol Manufacturer‌: Fully automated propellant filling system increased capacity to ‌5,000 cans/hour‌, achieving industry-leading leak-proof performance.

‌4. Value-Added Services and Global Reach‌

‌‌•Compliance Support‌: Assistance with ISO 22716, REACH, FDA 21 CFR 700, and other regulatory certifications.

‌•‌Legacy Line Upgrades‌: Modernize semi-automatic lines into smart, fully automated systems with AGV material handling and AI quality control.

•Localized Service Network‌: Technical centers in Southeast Asia and Europe provide ‌48-hour on-site support‌ and spare parts delivery.

‌Summary‌: Zhejiang Guoyu integrates ‌“precision filling + hygienic assurance + smart manufacturing”‌ to deliver end-to-end solutions for cosmetics and household chemical companies. Its innovations help clients address fast-changing market demands, stringent regulations, and sustainability goals, positioning the company as a strategic partner for industry advancement and global competitiveness.
