Efficiency is the single most important factor in a successful fruit box business versus one that has to deal with cost escalation, delays and waste. Efficient packaging lines generate higher units per hour, consume less material waste, require less manpower and adjust their operations to meet the customers' changing needs faster. In today's competitive fruit market where growers and retailers are looking for rapid turnaround and uniformity, there is no choice but to improve the efficiency of the operations. Here are four ways in which fruit box manufacturers are more efficient.
Advanced Forming Technologies with Multi - Material Capability
The main production process in the manufacture of fruit boxes is thermoforming or vacuum forming. These traditional machines using one or two materials lead to the production line being bottlenecked by switching. Today's manufacturers are well-equipped and invest in multi-material forming lines that allow them to process a variety of materials without long changeover times.
For instance, Xiamen Xiefa Vacuum Forming Packaging Co., Ltd. has achieved perfect processing technology for PP, PLA, CPLA, PBAT, PBS, cornstarch, PET, OPS and CPET. One multi material capability is the ability to produce clear PET berry clamshells, black PP grape trays and compostable PLA strawberry punnets, with relatively few tooling changes. This leads to improved overall equipment effectiveness (OEE) since changeovers are reduced from hours to minutes.
Additionally, advanced forming technology features servo driven indexing, accurate temperature control and in line trimming. These features improve cycle times, minimize scrap and ensure wall thickness uniformity in each cavity. This means more boxes per shift and lower box per cost for fruit box manufacturers.
Integrated Quality Management from Raw Material to Finished Product
Efficiency is more than speed, it's doing things right the first time. Rework, rejections and customer returns are the enemies of efficiency. These losses are prevented with a thorough quality management system.
Xiamen Xiefa has set up a scientific and complete quality management system, which is used in the process of quality control from the beginning to the end in raw material reception to finished product dispatch. The company is ISO 9001, 14001, 14007, BSCI, BRC, HACCP, GRS certified by SGS. There are documented procedures for incoming material inspection, in process checks and final product testing required for these certifications.
This requires verifying each roll of PET, PLA or RPET sheet for gauge consistency and clarity for fruit box production. The temperature, pressure and cycle time are monitored during forming. Automated vision systems or manual inspectors are used to inspect for flash, contamination or dimensional errors after trimming. The system is able to detect defects early, thereby avoiding a large amount of scrap. This translates into increased yield, reduced material costs and reduced customer complaints, leading to improved efficiency.
Custom Mold Design for Faster Cycling and Material Savings
Off-the-shelf molds are not usually designed to be fast or efficient with materials. Specific custom molds can be most effective in achieving fast cycle times and a minimal waste of sheets if they are made according to a fruit box geometry.
Computer aided design (CAD) and finite element analysis (FEA) are used by the experienced OEM/ODM manufacturers, such as Xiamen Xiefa, to optimize the mold geometry. Some of the design considerations are:
The even distribution of the thickness of the wall to reduce the cooling time.
Optimized draft angles for fast part ejection
Strategic ribs and corner radii for strength; less material.
Strong nesting layouts with high utilization of the sheets (usually > 85%)
A good designed mold can cut down the cycle time 15-25% and plastic sheet used per box will be cut down 5-10%. These savings add up to efficiency over millions of cycles. In addition, the faster the cycle, the faster a manufacturer can turn out orders without the need for any new forming lines.
Lean Workflow and After - Sales Support
The most effective forming technology and molds will actually not deliver optimal results if the entire process is uncoordinated. To use lean thinking, efficient manufacturers of fruit boxes have implemented raw material management, standardization of changeovers, preventive maintenance, production tracking, etc.
Xiamen Xiefa's lean production is coupled by a strict after sales service guarantee system. For buyers, this actually means technical support for mold installation, troubleshooting and availability of spares. A manufacturer that can actually quickly address production problems, such as an irregular heat or the need to trim a piece, away, minimizes downtime.
Moreover, the one-stop OEM and ODM solutions such as the packaging machines themselves enable customers to obtain both the production equipment and the boxes from a single supplier. This integration allows to streamline procurement, make it compatible and lower the learning curve for operators.
Summary
The four main strategies used by fruit box manufacturers to gain packaging efficiency involve investing in advanced forming machines capable of processing multiple materials, adopting a quality management system from the raw material to the finished product, creating custom molds for quicker cycle times and reduced material usage, and implementing lean workflows with responsive after sales support. Founded in 2009, Xiamen Xiefa Vacuum Forming Packaging Co., Ltd. offers all four with a wide range of material options (PP, RPET/PET, bagasse, paper, cornstarch, PLA, PS and more) and ISO and SGS certifications.
