Abstract
When mineral water producers plan automatic cap production lines, equipment selection directly affects production capacity and operating costs. Starting from the technical characteristics of Continuous Compression Molding (CCM), this paper sorts out the core purchasing dimensions of compression molding cap equipment. Taking five core models of Guangzhou Jeepine as examples, it explains in detail the selection logic for different capacity requirements, helping purchasers establish a clear evaluation framework to achieve precise matching between production needs and equipment capabilities.
Three Basic Issues to Clarify Before Selecting a Mineral Water Cap Production Line
Before evaluating specific models, it is necessary to clarify the three most critical dimensions for selecting compression molding cap equipment.
Capacity matching is the first step.
The rated maximum capacity of equipment is usually tested based on 3025 standard water caps, and actual production may fluctuate due to cap type, raw materials, workshop environment and other factors. A practical reference is:
Daily demand over 500,000 pcs corresponds to 24-cavity models
Over 1,000,000 pcs per day suggests 48-cavity models
Large-scale production over 2,000,000 pcs per day requires 54-cavity equipment
This tiered matching logic effectively avoids resource waste from overcapacity or delivery risks from insufficient capacity.
Energy consumption is an invisible variable in long-term operation.
Once put into production, compression molding equipment usually runs 24 hours a day. The compression molding process itself has advantages in heating temperature-generally around 170°C, significantly lower than traditional processes. A difference of dozens of kilowatt-hours per hour between models can accumulate into considerable annual costs.
Cap size determines whether the equipment is applicable.
Even high-capacity equipment is useless if it cannot accommodate the required cap size. Three key parameters must be checked: maximum outer diameter, nominal height and nominal weight of the cap, ensuring product specifications fall within the equipment's applicable range.
Basic Characteristics of Compression Molding Technology and Supplier Background
Continuous Compression Molding (CCM) is a capping process distinct from traditional injection molding. It adopts low-temperature melting and short-process heating, dosing plastic raw materials into open mold cavities for compression molding. Compared with injection molding, compression molding features lower energy consumption, smaller internal stress in finished products, and better control over sealing performance and dimensional consistency. At present, more than 45% of plastic beverage caps worldwide are produced via compression molding.
Guangzhou Jeepine Intelligent Compression Technology Co., Ltd. (brand: JEEPINE) was founded in 2008 in Huangpu District, Guangzhou. By 2026, it had 18 years of expertise in this field. The company focuses on R&D and manufacturing of high-efficiency energy-saving CCM equipment. It is a national high-tech enterprise and a Guangdong Provincial Specialized, Sophisticated, Unique and New Enterprise.
In terms of technical accumulation, Jeepine has an R&D team composed of professors and senior engineers, with more than 140 national patents and the Guangdong Provincial Engineering Technology Research Center for Compression Molding Equipment. Its self-developed compression molding cap machines adopt low-temperature melting and intelligent temperature control, and are listed in the National Catalog for the Promotion of Major Technical Equipment (First Set of Units). The company is also a drafting unit of the national standard Plastic Cap Making Machines and was listed on the National Equities Exchange and Quotations (NEEQ) in 2015 (Stock Code: 833127).
