Application Characteristics
1. Product type
- The base of the sun umbrella is mostly a hollow plastic structure, which can be filled with sand or cement to increase the weight. The common material is HDPE (high-density polyethylene), which has the characteristics of weather resistance, impact resistance and low cost.
- Various specifications: the diameter is usually 30-60cm, the weight is 5-20kg, suitable for different scenes such as beach umbrellas and garden umbrellas.
2. Process advantages
- Blow molding: suitable for the production of hollow, thin-walled, large-volume products, which saves more materials and has lower mold costs than injection molding.
- High production efficiency: The daily output of a single machine can reach hundreds, with a high degree of automation (automatic pickup and trimming).
Umbrella Base Blow Molding Machine Core Configuration
1. Equipment Composition
- Extrusion system: melt and plasticize HDPE granules, and extrude tubular parisons through screws.
- Mold system: blow the parison after the two halves of the mold are closed, and cool and shape it.
- Control system: PLC controls parameters such as temperature, pressure, and mold closing speed.
- Auxiliary equipment: crusher (recycle scraps), mixer (add masterbatch).
2. Selection points
- Clamping force: select according to the base size (usually 50-100 tons).
- Storage tank capacity: ensure continuous extrusion of large parisons (such as 5-10kg/cycle).
- Energy consumption: variable frequency motor can reduce power consumption.
Production Process
1. Raw material preparation
HDPE granules drying (optional) + masterbatch mixing → feeding into the extruder.
2. Blow molding
Melt extrusion parison → mold closing → high-pressure air blowing → cooling and shaping → mold opening and taking out.
3. Post-processing
Trimming flash → drilling (preparatory water injection/sand mouth) → quality inspection (wall thickness uniformity, sealing).
Market And Innovation Trends
1. Demand driven
The growth of the outdoor leisure industry (camping, commercial sunshade facilities) drives the demand for bases.
Environmental requirements: application of recyclable HDPE or bio-based plastics.
2. Technology upgrade
Multi-layer co-extrusion blow molding: Enhance the UV resistance of the base (add anti-aging agent to the outer layer).
Automation integration: Robot stacking, online weighing and sorting system.
Common Problems And Solutions
Problem 1: Uneven wall thickness
→ Adjust the parison control program or mold venting design.
Problem 2: Surface sink marks
→ Optimize the cooling water path or reduce the melt temperature.
Umbrella base blow molding machine has become the mainstream production equipment with its advantages of high efficiency and low cost, and will develop towards intelligent and environmentally friendly materials in the future. When purchasing, it is necessary to match the equipment parameters according to the product size, output and raw material characteristics, and pay attention to mold design and process optimization to improve the yield rate.
