BUBULE’s factory spans 45,000 m² and brings 28 years of experience in the research and production of PP luggage. The facility is divided into specialized zones, including injection molding, accessory assembly, lining production, and quality inspection. With 8 main workshops, 88 injection molding machines, 60 sewing machines, and 15 automated production lines, the factory integrates robotic arms and conveyor systems to create a modern, semi-automated facility capable of producing over 10,000 luggage pieces daily. Continuous R&D and technological upgrades ensure material independence and innovation, while stringent quality control in a clean, standardized environment includes over 30 inspection steps, compliant with ISO9001 and ISO14001 standards.

Injection Molding Workshop (Luggage Components Production)

Handles the full process from raw material to finished accessories. Precise temperature control and pressure monitoring ensure dimensional accuracy and structural strength, supporting critical luggage components such as wheels, static handles, and telescopic handles.

Accessory Workshop (Telescopic and Static Handles, Wheels)
  • Telescopic Handles: Cold-stamped aluminum tubes are assembled and repeatedly inspected for quality before integration into the final product.
  • Wheels: Bearings are automatically pressed into high-strength PA cores covered with soft TPU, providing quiet, smooth performance. Wheels withstand 12 km of loaded travel with minimal wear (< 0.3 mm).
  • Integrated Workflow: All units collaborate to ensure consistent capacity and quality.

Quality Control

All raw materials are virgin plastics enhanced with additives to improve impact resistance and oxidation durability. Each batch undergoes rigorous testing, including impact test, tensile test, and melt flow rate test, ensuring compliance with QB/T 2155-2018 standards and local regulations.

Melt Flow Rate (MFR) Tester
Melt Flow Rate (MFR) Tester: Used to measure the flow rate of plastics and resins under shear conditions, ensuring consistency and quality in the molding process.
Impact Tester
Impact Tester: Evaluates the impact toughness of plastic materials such as PP, ABS, and PA. This test compares different formulations to ensure molded products meet impact resistance requirements and supports the development of high-toughness materials.
Universal Testing Machine
Universal Testing Machine: The universal testing machine is designed to evaluate the mechanical properties of both metal and non-metal materials. With additional fixtures and accessories, it can test products for tensile strength, compression resistance, peel strength, tear resistance, bending, three-point flexural strength, and shear resistance. Tests can be performed and data analyzed according to multiple standards, including GB, ISO, JIS, ASTM, DIN, or any customer-provided specifications.
Luggage Testing
PP Shell Rolling Test
PP Shell Rolling Test

Simulates extreme usage conditions to verify compression resistance. During testing, the PP shell is placed on a flat surface and subjected to repeated pressure from a standard loaded vehicle, while deformation and cracking are monitored in real time. This rigorous test ensures the shell maintains structural integrity under everyday collisions, pressure, and rough handling, providing reliable luggage protection.

Luggage Caster Mileage Test
Luggage Caster Mileage Test

Tested with a 15 kg load over 15 km; multi-directional spinner wheels pass with luggage wheel walking test.

Luggage Handle Jerk Test
Luggage Handle Jerk Test

Handles are tested under a 15 kg load for 1,500 cycles to ensure durability.

Luggage Handle System Test
Luggage Handle System Test

Under a 15 kg load, handles undergo 1,500 oscillation cycles (wide handles tested for 500 cycles), meeting quality standards.

Telescopic Handle Extension Test
Telescopic Handle Extension Test

Handles are tested for 4,000 extension cycles under a 15 kg load, passing all performance criteria.

Drop Test
Drop Test

Luggage loaded with 15 kg is dropped from a height of 1 meter; the shell withstands impact without damage.
