Disposable plastic gloves (such as PVC gloves) have become one of the first choices for many industries and personal protection due to their characteristics of no latex allergy risk, comfortable wearing, flexible use, good chemical resistance, significant protective effect, durability, and ease of use.
The process of producing and delivering PE gloves generally includes the following main stages:
1. * * Raw material procurement and inspection * *:
-* * Raw Material Selection * *: Choose high-quality polyethylene (PE) particles as the main raw material to ensure the durability and protective performance of the gloves.
-* * Raw material processing * *: Drying, screening, and impurity removal of PE particles to remove moisture, impurities, and foreign objects that may affect product quality, ensuring the quality and stability of the raw materials.
2. * * Melt extrusion * *:
-Heating and melting: The processed PE particles are fed into an extruder and melted into a uniform molten plastic through heating.
-Extrusion molding: Melted plastic is extruded through a mold to form a continuous thin film, and the thickness of the film is precisely controlled according to the glove specifications.
3. * * Blow molding and shaping * *:
-* * Glove mold * *: The film is blown through a specific mold, and there is a cavity corresponding to the shape of the glove inside the mold.
-* * Air inflation * *: Inject high-pressure air into the mold to make the film tightly adhere to the inner wall of the mold and expand into a glove shape.
-Cooling and shaping: The formed gloves are cooled inside the mold to solidify the plastic and form the basic structure of the gloves.
4. * * Cropping and Separation * *:
-* * Cutting *: Cut continuous film gloves along the predetermined position into individual gloves.
-* * Separation * *: Separate the left and right gloves by mechanical or manual means, ensuring that each glove is independent.
5. * * Quality inspection * *:
-Visual inspection: Conduct a visual inspection on each glove to ensure there are no obvious defects (such as holes, scratches, color differences, etc.).
-* * Functional testing * *: Conduct sealing tests, tensile strength tests, etc. as needed to ensure that the gloves meet the specified protection standards.
6. * * Packaging * *:
-* * Counting and packaging * *: Divide qualified gloves into a certain quantity (such as 100 pieces/pack).
-* * Sealing * *: Use automated equipment or manual methods to seal glove packaging to ensure it remains clean and sterile during transportation and storage.
-* * Labeling * *: Attach product labels on the packaging, including necessary information such as product name, specifications, production date, expiration date, manufacturer information, and usage instructions.
7. * * Warehousing and Logistics * *:
-* * Storage * *: The packaged gloves are stored in the warehouse and managed according to batch and storage location.
-* * Outbound shipment * *: Pick and pack according to customer orders, arrange logistics transportation, and ensure timely and accurate delivery to the customer's designated location.
8. * * Delivery and after-sales service * *:
-Handover acceptance: After receiving the goods, the customer conducts quantity verification and quality acceptance.
-* * After sales support * *: In case of quality issues or usage doubts, the manufacturer provides necessary technical support and return and exchange services.
The above is the general process from production to delivery of PE gloves, and each step may involve strict quality control measures to ensure the quality of the final product and the user experience. In the actual production process, the specific process details and sequence of processes may vary depending on the manufacturer.
The production of glove molds is a precise and complex process that involves multiple steps and technical requirements. The following is the general production process for glove molds (especially those used for producing latex gloves):
1. * * Design * *:
-Preliminary Design: Based on customer requirements and glove specifications, the designer uses CAD (computer-aided design) software to draw mold drawings, including the overall structure, dimensions, proportions of various parts, patterns, and other details of the mold.
-* * Simulation Simulation * *: Conduct fluid dynamics or thermodynamic simulation analysis to predict the flow of materials in the mold, cooling rate, and possible shrinkage, deformation, and other issues, and optimize mold design.
2. * * Material selection and preparation * *:
-* * Material selection * *: Choose mold steel or other suitable materials with good wear resistance, heat resistance, corrosion resistance, and thermal stability.
-* * Pre treatment * *: Heat treatment such as forging, annealing, and tempering is carried out on selected steel to achieve ideal hardness, toughness, and internal microstructure.
3. * * Mold processing * *:
-Rough machining: Using CNC milling machines, electrical discharge machining (EDM) and other equipment, rough contour cutting and rough grinding of the mold blank are carried out according to the design drawings to form a rough shape.
-* * Precision processing * *:
-* * Cavity machining * *: Fine milling or electrical discharge machining is performed on key parts of the mold, such as the finger and palm cavities, to ensure dimensional accuracy and surface smoothness.
-* * Pattern processing * *: If the mold needs to have specific patterns or textures, the corresponding patterns are processed in the mold cavity through carving, laser etching, and other methods.
4. Assembly and Adjustment:
-Assembly of Components: Accurately assemble the various components of the mold (such as upper and lower molds, sliders, inserts, etc.) together according to design requirements to ensure tight fit and smooth movement.
-* * Trial molding and adjustment * *: Conduct trial molding on a dedicated injection molding machine to observe the molding effect of latex gloves, such as dimensional accuracy, surface quality, demolding performance, etc. Make necessary mold corrections or adjustments based on the trial results, such as fine tuning the cavity size, improving the exhaust system, adjusting the gate position, etc.
5. * * Surface treatment * *:
-Polishing: High precision polishing of the mold cavity to improve surface smoothness, reduce friction between latex and the mold during the molding process, facilitate demolding, and improve the surface quality of gloves.
-Hardening treatment: nitriding, chrome plating, PVD coating and other hardening treatments are applied to key working surfaces to enhance the wear resistance and corrosion resistance of the mold, and extend its service life.
6. * * Inspection and Acceptance * *:
-Dimensional inspection: Use precision measuring tools to check whether the dimensions of each part of the mold meet the design requirements and ensure that they are within the tolerance range.
-Performance testing: Conduct necessary performance tests such as pressure resistance, temperature resistance, and corrosion resistance to verify the stability of the mold under actual production conditions.
-* * Quality Certification * *: If necessary, apply for mold quality certification in relevant industries or international standards (such as ISO).
7. * * Packaging and Delivery * *:
-Mold protection: After rust prevention treatment, the completed mold is packaged in a dedicated wooden or metal box, filled with shock-absorbing materials to ensure safety during transportation.
-* * Technical Documents * *: Provide detailed mold user manuals, maintenance manuals, 3D drawings, and other technical documents for customers to use and maintain molds correctly.
-* * Delivery and Installation * *: Transport the mold to the customer's site, assist the customer in installation and debugging, and ensure smooth production.
The above is the general production process of glove molds. The entire process requires a high level of professional skills, precise processing equipment, and strict quality control to ensure that the mold can efficiently and stably produce latex gloves that meet the requirements.
