The exquisite small hard-shell boxes that we see are generally called luxury boxes. These products are sturdy, fashionable in appearance, and come in various styles, and are widely used in gift packaging, such as high-end tobacco and alcohol products, mobile phones, MP3 players, etc. The production process and equipment are relatively simple
一. Production process
The production equipment is quite simple, mainly consisting of: a semi-automatic water-spraying machine, a corner-attaching machine, a flat press, as well as plastic boards, brushes, glue bottles, glue guns, cutting knives, flat-mouth clamps, etc. The materials used include gray cardboard, fabric (special fine paper, magnets, silk cloth), glue, alcohol, white gasoline, rags, adhesive paper, etc. The process flow is as follows:
1. Preliminary preparation
According to the customer's production requirements, prepare and verify the necessary materials and sample boxes,
2. Tearing off the edge material
First, tear off the surrounding waste material from the single-sided coated gray-backed white paperboard and the face paper beer-made semi-finished product, sort and label them for future use. When tearing off the material, check whether the beer-made product has been damaged.
3. Box blank forming
According to the product material and process requirements, use a corner gluing machine or high-gloss adhesive tape for corner reinforcement and shaping (adhesive splicing of box blanks should be done after the glue dries to prevent falling apart and deformation). During the operation, ensure that the corners are glued flush and securely, without any looseness or excessive glue. For boxes that require embedded magnets or ribbons, the hole positions should be pre-drilled for future use,
4. Mounting face paper, edging, and wiping
To start the glue machine, if using a hot flame glue machine, set a preheat temperature of 100℃ in advance. The startup temperature is generally set to: 75~80℃ in summer and 90~95℃ in winter. If the temperature base is too low, the glue will deteriorate, and conversely, the drying time will be faster, making production operations difficult. After gluing, lay the glued fabric flat on the workbench, align it correctly according to the speed line position (or the drawn line position), then apply the fabric to the gray paperboard, and use a scraper or a clean cloth to wrap and wipe the edges. During the operation, the damaged seam allowance of the box should be pasted inside, following the sequence from the surface to the edge, from the outside to the inside, and from the gold base to the box body. During the operation, be careful to prevent defects such as graying, edge overhang, slanting, bubbling, wrinkling, and scratching (marks). After wrapping and pasting, immediately use a clean cotton and linen cloth to wipe away any excess or sticky glue.
5. Homework notes
For fabrics with national inspection and color position requirements, as well as for back tube paper and internal pasting, attention must be paid to centering and alignment. After pasting the leather shell, excess waste material must be promptly removed to prevent damage to the thread. The box body surface, product corner positions, edging positions, and seam positions should be scraped firmly with a scraper (prohibited for matte adhesive fabrics). If necessary, use a cloth to smooth it out to prevent glue separation and bubbling. After pasting, it is required to achieve a flat, clean, and angular appearance.
6. Assembled finished product
According to the BOM box structure and relevant requirements, apply glue to the parts to be assembled in a "。" shape using a glue bottle or brush. Then, bond and assemble the components into a set. During the application of glue, control the amount of glue and the application position, which is generally 2~3mm away from the edge of the product. Wait for the glue to dry slightly before proceeding with the assembly. When assembling, press slightly with external force for a moment to ensure complete bonding. If necessary, use a flat surface to tighten to prevent the occurrence of glue separation or peeling. Depending on the need, iron blocks can be used for pressure treatment on the board. Objects with assembly requirements (such as inner trays) should be assembled according to the BOM requirements. Complex box types should be assembled following the relevant process flow of "separation before assembly".
7. Timely self-inspection: Operators should conduct self-inspection at any time during the production process, and quality control (PQC) should cooperate with them to conduct random inspections. Before the finished products are stored, they must undergo a full inspection and cleaning process, and can only be stored after confirmation by PQC. Defective products should be clearly marked and placed separately,
8，After postpartum cleaning： semi-finished or finished products should be neatly and orderly placed on pallets, and product identification should be promptly carried out, while paying attention to the way of placing the boards. Panel, box lid, and surround semi-finished products should be stacked bottom-to-bottom. Finished products can be placed in a upright or sideways position depending on the specific box structure and size. Each 2-3 layers should be padded with paper, and the height should not exceed 8 layers to prevent excessive load-bearing, which may cause indentation, deformation, and poor jointing. When finished products are stored, paper corner protectors and plastic film should be used around them, and the top should be covered with a cardboard to prevent dust. If products need to be packed (stored), each packaged product should be promptly identified and inspected to prevent mixing.
二. Attention Points
1，For fabrics with colored patterns, it is advisable to use white latex adhesive for mounting (with a slow drying time) to facilitate timely adjustments in case of positional deviations.
2. Properly use various glues. For surface-treated fabrics such as those treated with over-glossing and acrylic, avoid using glues containing benzene components (such as universal pattern) to prevent chemical reactions that may cause bubbling. In case of glue spillage or adhesion during operation, select the appropriate cleaning method based on the fabric material. It is not advisable to use thinner (containing benzene components) for surface-treated fabrics. Special paper materials should not be cleaned with wave-state cleaners. Instead, use a dry cloth or rubber to wipe them clean to prevent fading and deterioration. The rags used for wiping should be replaced promptly and recycled in the designated trash bin.
3. Operators must handle products gently when transporting and contacting them to prevent scratches, indentations, and falling over
4. The laminated fabric should be designated to the laminating personnel for taking, to prevent misuse. Operators are prohibited from having long nails. When handling laminated paper, specialty paper, and bronzing fabrics, finger cots should be worn, and it is not advisable to directly use hard auxiliary tools such as scrapers, to avoid causing scratches and indentation marks
