Detailed Process
- Material Preparation & Rubber Mixing
Select high‑purity food‑grade eco‑friendly silicone raw materials and conduct professional mixing and color matching with food‑grade compliant eco‑friendly color masterbatch. Proportion raw materials strictly in accordance with product hardness, thickness, weight and compression‑resilience indicators and cut rubber materials with precise quantification. Impurities and defective rubber materials are screened and eliminated throughout the process to unify the hardness, color and elasticity parameters of each batch, ensuring safety compliance, consistent quality and stable sealing performance of finished wine stoppers from the source.
- Mold Preheating
Conduct deep cleaning on the dedicated precision molding mold for wine bottle stoppers to completely remove internal dust, residual rubber and oil impurities. Fix the mold on a hydraulic vulcanization machine for constant‑temperature preheating and parameter debugging, accurately set molding temperature, pressure and vulcanization time to stabilize molding conditions, and ensure subsequent molded wine stoppers feature precise outline, bottle‑neck‑matching dimension, smooth surface and zero molding defects.
- Feeding & Mold Closing
Accurately place quantified and qualified food‑grade silicone raw materials into the mold cavity with precise alignment. Perform multiple exhaust treatments after mold closing to fully discharge internal air, effectively avoiding finished product defects such as bubbles, material shortage, dents and uneven thickness, and ensuring complete outline, standard conical surface and controllable dimensional tolerance of wine bottle stoppers.
- High‑temperature Vulcanization
Adopt constant‑temperature and pressurized high‑temperature vulcanization process to realize sufficient cross‑linking and curing of silicone raw materials and seamless integrated molding of wine bottle stoppers. The finished product features compact structure and uniform elasticity, with greatly improved compression‑resilience, tear resistance, alcohol resistance and aging resistance. It is not easy to deform, harden or fail after repeated plug‑and‑pull squeezing, wine soaking and long‑term storage, achieving significantly extended service life.
- Demolding & Shaping
Open the mold stably after vulcanization and take out complete wine stopper blanks. Adopt natural air cooling shaping technology with precise temperature control for slow cooling and curing to release molding internal stress, effectively eliminating twisting, local deformation and dimension offset, and ensuring the standardization, flatness and dimensional consistency of all finished wine stoppers.
- Fine Trimming Treatment
Carry out manual fine trimming and chamfer polishing on cooled and shaped wine stopper blanks to completely remove excess edge burrs and sharp edges, and polish all outlines to be round, smooth and flat without sharp corners. Improve the overall delicate texture and plug‑and‑pull hand feel of products, avoid scratching bottle‑neck glass, and meet high‑quality wine‑ware customization standards.
- Surface Cleaning & LOGO Positioning
Before epoxy dropping, perform dust‑free cleaning on the wine stopper surface to remove dust, oil stains, static electricity and residual impurities, ensuring the silicone surface is dry, clean and free of floating dust. Perform precise positioning according to the customer’s high‑definition LOGO source file, and fix the LOGO position using a positioning jig or visual positioning method to ensure the LOGO of each batch is centered, consistent in angle and unified in size, avoiding misalignment, skew and inconsistent size.
- One‑color Printed Dome Epoxy Logo Customization & Curing
Perform dome epoxy processing on pre‑positioned LOGO areas. Print the base color or outline of the LOGO first, then dispense transparent epoxy dome resin, which self‑levels to form a full rounded dome surface. Strictly control dispensing volume, speed, dispensing path and edge finishing to avoid overflow, insufficient resin, bubbles, pinholes and uneven thickness. Carry out constant‑temperature curing after dispensing to achieve full cross‑linking of epoxy resin. The finished 3D LOGO features clear surface, smooth edge, uniform gloss and strong adhesion. The cured LOGO delivers good scratch‑resistance, abrasion‑resistance, water‑washing resistance, alcohol‑wiping resistance and low yellowing performance. It resists peeling, blurring and yellowing under normal service conditions.
- Post‑processing, Quality Inspection & Warehousing
After epoxy curing, conduct secondary high‑temperature deodorization and sterile cleaning on finished products to completely eliminate residual slight raw material odor and ensure safety under wine‑contact conditions. Carry out full‑dimensional final quality inspection covering key indicators such as appearance flatness, outline standardization, dimensional tolerance, silicone compression‑resilience performance, dome epoxy LOGO position, resin fullness, edge smoothness, adhesion, alcohol‑wiping resistance, yellowing resistance and food‑grade safety compliance. All qualified products are sterilely and individually packaged and stored in classified warehouses, fully complying with the safety access and batch delivery standards for customized daily wine‑ware products.
