As a manufacture in the plastic rubber industry, you first need to understand what the machines is for, its application, price range, and the prodcution prodcesses for the finished products.
I. What is a PVC Dispensing Machine?
A PVC dispensing machine (also called an automatic PVC dispensing machine or soft glue dispensing machine) is a CNC automated dispensing device specifically designed for PVC paste resin (Plastisol) soft glue products.
Core Function: Replaces manual labor by precisely dispensing different colored PVC pastes into aluminum/copper molds. After high-temperature baking and curing, it forms three-dimensional soft glue products, widely used in the production of small commodities, clothing accessories, and gifts.
Raw Material Principle: PVC paste + plasticizer + colorant are mixed to form a color paste. The machine dispenses a measured amount into the mold, and baking at 160–190℃ causes a gel reaction. After cooling, it becomes a soft and elastic PVC soft glue product.
II. Core Structure of the Machine
Three-axis servo motion platform (XYZ)
Servo motor + ball screw, repeatability 0.01mm, smooth path, no glue leakage; two stroke options available: small table (500×350) and large table (700×900).
Multi-color glue supply system: Standard configuration includes 6/8/12/18/24 color pressure hoppers + independent dispensing valves, with individual pressure and timing control for each color; high-end models feature a constant-temperature material pipe throughout the process to prevent PVC paste from thickening and clogging the nozzles.
CNC control system: Industrial touchscreen + teach pendant, supports DXF graphic import and hand-drawn teaching; can store hundreds of mold programs, retrieved with one click, supporting simultaneous production of multiple molds.
Frame and worktable: Thickened steel plate welded for shock resistance; tabletop for placing aluminum molds and brass drip molding molds; equipped with an air pressure regulating module (0–6kg adjustable air pressure).
Auxiliary accessories: Vacuum pump (for raw material degassing), constant-temperature oven/tunnel oven, water-cooled cooling platform, base material dispensing machine, 3D mold assembly machine (for three-dimensional figurines).
III. Mainstream Machine Classification
1. Desktop Small Standalone Machine (6-8 Colors)
Suitable for: Small workshops, shoe labels, bag labels, small refrigerator magnets
Parameters: 220V, power 1-1.5KW, tabletop 550×350mm
Advantages: Small footprint, low price (20,000-40,000 RMB), can be operated by one person
2. Large Tabletop Multi-Color Machine (12/18/24 Colors)
Suitable for: Complex multi-color keychains, cartoon dolls, large-area bar mats, shoe soles
Advantages: Multi-color simultaneous dispensing, fast speed, replaces 3-4 dispensing workers, accuracy ±0.001g dispensing error
3. Fully Automatic Dispensing Production Line (Complete Line)
Composed of multi-color dispensing machine + double-layer tunnel oven + cooling table + base material machine + water-cooled demolding, continuous automated production, suitable for large-scale factories, saves more than 30% of electricity, 24-hour uninterrupted mass production. 4. 3D Molding Machine Equipped with upper and lower molding dies, this machine produces 3D PVC figurines, pendants, and cartoon ornaments. It can produce double-sided colored 3D products.
IV. Standard Production Process
**Ingredient Mixing and Vacuuming:** Mix PVC paste and colorant, then use a vacuum pump to degas (eliminate air bubbles in the finished product).
**Programming and Machine Setup:** Place the mold on the worktable, import the pattern program, or manually teach the glue path.
**Automatic Color Dispensing:** Multi-color needles dispense the corresponding color blocks layer by layer according to the pattern.
**Initial Baking and Coloring:** Bake in a tunnel oven at approximately 170℃ to cure and set the colored layer.
**Water Cooling:** Cool the mold to prevent the underlying pattern from being damaged by high temperatures.
**Base Material Injection:** The base material machine fills the bottom layer of the mold, increasing the product's thickness and toughness.
**Second Baking:** The base material is fully cured.
**Water-Cooled Demolding:** After cooling, peel off the mold and trim the edges to obtain the finished product.
V. Applicable Product Range
**Clothing Accessories:** PVC shoe labels, clothing logos, bag tags, zipper pulls
**Gifts and Cultural Products:** Cartoon keychains, 3D figurines, refrigerator magnets, coasters, bar counter anti-slip mats
**Daily Necessities:** PVC anti-slip mats, soft rubber patches for mobile phones, watch straps, photo frames
**Automotive/Industrial:** Anti-slip floor mats for car interiors, soft rubber buttons, grip covers
**Shoe Materials:** PVC PVC Drip Molded Shoe Soles, Shoe Heel Strips, and Shoe Upper Decorative Pieces
VI. Core Advantages
High Precision and Stability: Servo-controlled quantitative glue dispensing ensures uniform thickness and a yield rate of 95%+, significantly saving PVC raw materials.
Labor Saving: One 12-color machine equals 3-4 skilled workers, resulting in lower long-term production costs.
Multi-Color Synchronization: Up to 24 colors can be processed simultaneously, allowing for one-time molding of complex color patterns.
Easy Operation: Graphic import/teaching mode; beginners can learn programming in 1-2 days.
Durable and Long-lasting: Imported servo motors and stainless steel material tanks ensure low failure rate during 24-hour continuous operation.
Multi-Purpose Machine: Different products can be switched by changing the mold; compatible with small-batch production of PVC and liquid silicone.
VII. Basic Selection Reference
