APEX Machinery proudly presents our Custom 24mm Pump Cap Injection Molding Machine—a precision-engineered system designed specifically for the efficient production of 24mm pump caps. Pump caps are essential dispensing closures widely used in the cosmetic, personal care, pharmaceutical, and household chemical industries, offering consumers controlled dispensing and convenient one-handed operation . Our custom 24mm pump cap machine delivers the precision, reliability, and productivity required for these demanding applications, with flexible configurations tailored to your specific production requirements.
Pump caps, also known as dispensing pumps or lotion pumps, are multi-component closures that typically consist of a cap body, dip tube, pump mechanism, and often an actuator. The 24mm neck finish size is one of the most common standards in the industry, used for a wide variety of products:
Cosmetics and Personal Care
Lotion and cream dispensers
Shampoo and conditioner bottles
Body wash and shower gel containers
Facial cleanser and serum packaging
Pharmaceuticals
Liquid medication dispensers
Topical treatment applicators
Sanitizer and antiseptic bottles
Household Products
Liquid soap dispensers
Cleaning solution bottles
Detergent containers
1. Specialized Design for 24mm Pump Caps
Our injection molding machine is specifically engineered for the unique requirements of 24mm pump cap production:
Precision cavity configurations: Available in 4 to 32 cavities depending on production volume requirements
Optimized for 24mm neck finish: Tooling designed specifically for this industry-standard size
Compatibility with various pump designs: Accommodates different actuator styles and pump mechanisms
Enhanced material distribution: Ensures consistent wall thickness for reliable pump function
2. Precision Hot Runner Systems
The hot runner system is critical for pump cap quality, particularly for the complex geometries involved. APEX's machines feature advanced hot runner systems with:
Individual temperature control for each nozzle, maintaining accuracy within ±1°C
Balanced filling across all cavities ensuring consistent cap dimensions and pump seating surfaces
Valve gate technology providing clean gate vestige on non-visible areas
Optimized material flow preventing defects in thin sections and critical sealing areas
3. High-Performance Plasticizing Unit
Our machines feature plasticizing units optimized for the materials commonly used in pump cap production:
HDPE and PP processing capability with specially designed screw geometries
Superior melt quality ensuring consistent material properties throughout the shot
Precise temperature control preventing material degradation
Fast color change capability for manufacturers requiring production flexibility
4. Robust Clamping System
The clamping unit provides stable, reliable mold closure throughout the injection cycle:
Clamping forces from 80 to 300 tons depending on cavity configuration
Generous tie-bar spacing accommodating pump cap molds
Precision guidance systems ensuring consistent platen alignment
High-speed operation without compromising stability
APEX Machinery offers custom 24mm pump cap machines in various cavity configurations to match your specific production requirements:
| Cavity Count | Ideal Application | Approximate Output |
|---|---|---|
| 4-8 cavities | Small-scale production, prototype development, specialty designs | 2,000-8,000/hour |
| 12-16 cavities | Medium-volume production, regional manufacturers | 8,000-20,000/hour |
| 24-32 cavities | High-volume production, established suppliers | 20,000-40,000/hour |
The specific output depends on pump cap complexity, weight, and material selection. Our engineering team helps you select the optimal cavity configuration for your production needs.
Our custom 24mm pump cap machine is compatible with all materials commonly used in pump cap production:
HDPE (High-Density Polyethylene): Most common material for cap bodies
PP (Polypropylene): Offers different flexibility and chemical resistance properties
LDPE (Low-Density Polyethylene): For softer, more flexible components
PP+PE combinations: For multi-material pump designs
Efficient cooling is essential for achieving fast cycle times and consistent pump cap quality:
Optimized cooling circuit design with spiral channels ensuring rapid, uniform heat extraction
Enhanced cooling in critical areas such as thread-forming regions and pump seating surfaces
Post-mold cooling options for applications requiring extended cooling
Temperature control accuracy ensuring dimensional stability
Our custom 24mm pump cap machines incorporate advanced energy-saving technologies:
All-electric servo drive options achieving energy savings of up to 50-70% compared to conventional hydraulic machines
Servo-hydraulic systems with variable speed pumps matching power consumption to demand
Kinetic energy recovery systems capturing and reusing energy during deceleration phases
Zero power consumption during cooling periods as servo motors can come to a complete stop
Quality assurance is essential for pump cap production, as these closures must provide reliable dispensing and leak-free performance. Our machines can be equipped with comprehensive quality monitoring:
Inline vision inspection systems performing multiple quality checks on each cap
Weight monitoring ensuring consistent material usage across all cavities
Dimensional verification confirming critical pump seating and thread specifications
Real-time rejection of defective parts guaranteeing that only quality caps proceed to downstream operations
