I. Requirement Communication and Solution Design
1. Requirement Understanding
This is the starting point of the entire customization process, and it is of great significance to have a comprehensive communication with customers. When understanding the application scenarios, if the tape is used for fixing precision components of electronic devices, it needs to have characteristics such as anti - static, high - precision adhesion, and no pollution residue. If it is applied to outdoor building waterproof sealing, then weather resistance, waterproofness, and strong adhesion are the key considerations. Regarding performance requirements, in terms of adhesion, it is necessary to clarify whether it is a strong initial adhesion for quick bonding or a long - lasting adhesion to ensure long - term fixation without falling off. For temperature resistance, the operating temperature range needs to be determined. For example, in a high - temperature industrial environment, it may need to withstand over 100 degrees Celsius, and in a low - temperature environment, the flexibility and adhesion of the tape should be ensured without damage. In terms of specification dimensions, precise control of length, width, and thickness can meet the needs of different packaging and bonding areas. For instance, narrow tapes are used for packaging small handicrafts, while wide and thick tapes are used for bundling large mechanical parts. There are various packaging forms. Carton packaging is delicate and suitable for gift tapes. Plastic bag packaging is convenient and economical for daily civilian use. Heat - shrink packaging provides strong protection with a tight fit and is often used for industrial batch products. The order quantity determines the production scale and cost allocation, and the delivery time affects the production schedule and logistics arrangement, all of which need to be mastered in detail.
2. Solution Provision
Relying on the knowledge reserve and rich experience of the professional team, targeted solutions are provided according to customer requirements. When recommending the type of adhesive, acrylate - based adhesives are often suitable for general daily - use tapes, with moderate adhesion and controllable costs. Rubber - based adhesives are outstanding in terms of temperature resistance and aging resistance and are mostly used for industrial tapes. Silicone - based adhesives have excellent high - and low - temperature resistance, insulation, and other characteristics, meeting the needs of high - end electronics and other fields. In terms of substrate material selection, plastic films such as BOPP (biaxially oriented polypropylene) film have high transparency and good tensile strength and are common substrates for sealing tapes. Paper substrates are environmentally friendly and have strong printability, often used for label tapes. PET (polyethylene terephthalate) film has high - temperature resistance and excellent mechanical properties and is suitable for special industrial tapes. The additive formula can adjust the flexibility, anti - aging, flame - retardant, and other properties of the tape. The costs of each solution are explained in detail, allowing customers to weigh the cost - performance ratio. For example, adding a UV absorber to improve weather resistance will increase the cost, but it can extend the service life of outdoor tapes.
3. Sample Production
According to the solution selected by the customer, a small number of samples are produced in strict accordance with production standards. The production standards cover aspects such as the accuracy of raw material ratio, the setting of production equipment parameters, and the standardization of process operation procedures. This ensures that the samples can truly reflect the performance and quality of the final product, allowing customers to directly experience the adhesion effect, tensile strength, appearance texture, etc. of the tape, providing an accurate reference for subsequent large - scale production.
II. Raw Material Procurement and Inspection
1. Procurement
According to the customization solution and order scale, various raw materials are accurately purchased. High - quality suppliers are the key to ensuring the quality of raw materials. For substrate suppliers, it is necessary to examine the stability of their production processes, such as whether the extrusion and stretching processes of plastic film production are mature, and the quality of papermaking raw materials and the control of the papermaking process of paper suppliers. The R & D capabilities and product batch stability of adhesive suppliers are crucial to ensure that key properties such as adhesion are consistent for each supply. Additive suppliers need to ensure that the purity, activity, etc. of the additives meet the requirements. Reliable suppliers are selected through multiple channels such as screening and on - site inspections, and quality guarantee contracts are signed to ensure the stable supply of raw materials.
2. Inspection
A comprehensive "physical examination" is carried out on the purchased raw materials. For appearance inspection, check whether the substrate has defects, uneven color, and whether the adhesive has precipitation and stratification. Dimension measurement ensures that the thickness and width of the substrate are accurate and meet the customized specifications. In physical property tests, the tensile strength test reflects the ability of the substrate to withstand external forces, the flexibility test ensures the adaptability of the tape during bending and winding operations, and the adhesive adhesion test is determined by the standard peel test. For chemical property testing, a thermal aging chamber is used to simulate different temperature environments for temperature resistance, and the tape is soaked for a certain period of time to observe the change in adhesion for water resistance. Only raw materials that meet all the indicators can enter the production line.
III. Production and Processing
1. Ingredients Preparation
Strictly in accordance with the requirements of the customized formula, with the assistance of high - precision weighing equipment, various raw materials are accurately weighed. Taking an electronic scale as an example, the accuracy can reach the milligram level to ensure that the ratio of the adhesive and additives is precise. A slight deviation in the ratio may cause fluctuations in the tape's performance. For example, if there is less adhesive, the adhesion will be insufficient, and if there are too many additives, it may affect the flexibility or curing effect of the tape, thus ensuring the stable output of the tape's performance.
2. Coating
The prepared adhesive is evenly spread on the substrate. The regulation of the parameters of the coating equipment is the key in this process. The coating speed affects the uniformity of the adhesive layer thickness. If it is too fast, uneven coating may occur, and if it is too slow, the production efficiency will be affected. The pressure adjustment ensures that the adhesive is closely adhered to the substrate. Insufficient pressure is likely to cause delamination, and excessive pressure may damage the substrate. Temperature control is related to the fluidity and initial curing of the adhesive. An appropriate temperature enables the adhesive to be smoothly coated and initially cured stably. By real - time monitoring and adjusting these parameters, precise control of the thickness and uniformity of the adhesive layer is achieved.
3. Drying and Curing
The coated tape enters the "transformation" stage of drying and curing. Drying volatilizes the solvent in the adhesive, and curing forms a stable adhesive structure. Different types of adhesives require vastly different drying and curing temperatures and times. For example, solvent - based adhesives generally require relatively high drying temperatures and long times to fully volatilize the solvent, while water - based adhesives require relatively milder temperatures. The curing process is similar. Thermosetting adhesives need to be precisely controlled in temperature and time to complete the cross - linking reaction, and photocuring adhesives need to be matched with specific wavelength light and duration. Precise control of these parameters ensures the final adhesive quality of the tape.
4. Slitting and Rewinding
According to the width required by the customer, the dried and cured tape is cut into strips using sharp and precise slitting knives. During the slitting process, the width of the tape is monitored in real - time, and the error is controlled within a very small range to ensure that the width of each roll of tape is consistent. In the rewinding process, it is operated according to the specified length and diameter, and the cut tape is wound into a finished roll to ensure tight, neat winding and a good appearance, which is convenient for subsequent packaging, transportation, and use.
5. Packaging
According to the customer's packaging instructions, the finished tape is properly packaged. For carton packaging, attention is paid to the structural design to ensure that the tape is stable in the box, and exquisite printed labels highlight the brand and product information. When selecting materials for plastic bag packaging, moisture - proof and flexible properties are considered, and the heat - sealing process is tight to prevent leakage. Heat - shrink packaging uses heating to make the film shrink tightly against the tape, providing strong protection. Throughout the packaging process, care is taken to protect the tape from scratches and pressure damage, and key information such as specifications, models, and production dates is clearly marked for easy identification and traceability by customers.
IV. Quality Inspection and Control
1. Process Inspection
"Quality sentry posts" are set at each production process node. During coating, a high - precision thickness gauge is used to monitor the thickness of the adhesive layer in real - time. If the deviation exceeds the allowable range, the coating parameters are adjusted immediately. During slitting, the width and edge flatness of the tape are checked with the help of a visual inspection system or manual sampling to prevent problems such as inconsistent widths and rough edges, ensuring that the output of each process meets the quality standards and nipping problems in the bud.
2. Finished Product Inspection
A "comprehensive physical examination" is carried out on the completed tape. In terms of appearance, the flatness is checked to see if there are wrinkles and bulges, and the presence of bubbles and scratches is inspected to ensure a flawless appearance. Dimension measurement reviews the accuracy of length, width, and thickness. In physical property tests, the adhesion is tested by a standard peel testing machine at different speeds and angles, the tensile strength is tested by a universal material testing machine to simulate external force stretching, and the initial adhesion is judged by the rolling ball method to measure the rolling distance of the ball. Chemical property testing simulates harsh environments such as high temperature, high humidity, and acid - base, and observes the performance changes of the tape. Only products that meet all the indicators can be shipped.
3. Quality Traceability
A complete quality traceability "database" is established, and detailed information on the entire production process of each batch of tape is recorded. The batch number of raw materials is traced back to the supplier and the purchase time. The production time is accurate to the second. The production equipment number is associated with equipment maintenance and parameter setting records. The operator's work number corresponds to training and operation proficiency. Once a product quality problem occurs, the root cause can be quickly locked according to the records. For example, if there is a problem with a certain batch of adhesive, the relevant products are recalled in a timely manner, and the production process is rectified to avoid the expansion of the problem.
V. Logistics and Distribution and After - sales Service
1. Logistics and Distribution
Combining customer requirements and order volume, a suitable logistics method is selected. For a small number of high - value tapes, express delivery services such as SF Express can be chosen to ensure fast and safe delivery. For batch industrial tapes, logistics dedicated lines such as Deppon can be considered, which are cost - effective and can ensure transportation protection. In - depth cooperation with logistics companies is carried out to customize special packaging and fixation plans to prevent transportation damage, and real - time logistics tracking links or information are provided, allowing customers to know the "whereabouts" of the products at any time.
2. After - sales Service
A comprehensive after - sales service system is constructed. In terms of product use consultation, hotlines and online customer service are set up to answer customers' questions about tape application scenario expansion, operation skills, etc. For complex problems such as the adaptability of the tape in a special process environment, technical experts are dispatched to provide on - site assistance. The handling of quality problems follows the principle of quick response. Once a complaint is received, an investigation is immediately launched. The cause is found according to the quality traceability system, and a solution is given within 24 hours, such as replenishment, replacement, or technical rectification. Customers are regularly followed up, and satisfaction, opinions, and suggestions are collected quarterly or semi - annually to continuously optimize products and services.
