Dongguan Zhenying Machinery Equipment Co., LTD
For multi-color designs, dispensing accuracy is one of the most important factors. Automated equipment helps manufacturers improve repeatability, maintain color alignment and reduce dependence on manual dispensing.
The manufacturing process begins with product artwork. The design defines the shape, dimensions, colors and three-dimensional layers of the finished keychain.
The artwork is then converted into a production file that defines the dispensing path for each color and layer. A customized mold is prepared according to the product structure, with separate cavities or areas for different PVC colors.
Accurate mold design and positioning are important for achieving a clear product outline and consistent layer structure.
Liquid PVC materials are prepared according to the required colors and product specifications. Each color is placed in a separate material barrel or dispensing channel.
Proper material preparation helps maintain stable flow and consistent product quality. Depending on the complexity of the design, manufacturers may use multiple colors to produce detailed logos, cartoon figures or customized patterns.
The prepared materials are then connected to a PVC Dispensing Machine.
PVC dispensing is the key stage in 3D PVC keychain production.
The mold is placed on the working platform, and a programmed dispensing system controls the movement of the dispensing head according to X, Y and Z coordinates.
A Multi Color 3D PVC Keychain Automatic Dispensing Machine can automatically dispense different colors of liquid PVC into designated mold areas. This helps manufacturers improve repeatability and control material usage.
For detailed multi-color products, positioning accuracy is especially important. Equipment with ±0.01 mm repeat positioning accuracy can help reduce dispensing offset and maintain alignment between different colors.
Depending on product requirements, manufacturers may choose 12-color, 18-color or 24-color configurations.
After the first PVC layer is dispensed, it is heated to allow the material to form and stabilize.
Most 3D PVC keychains are produced layer by layer:
This method creates the raised structure and three-dimensional appearance of the finished product.
Stable positioning between layers is essential because even a small deviation may affect color alignment and product appearance.
After all layers have been completed, the PVC product is cooled and removed from the mold.
Excess material may be trimmed before the keychain is assembled with accessories such as metal rings, chains, hooks or connectors.
The finished products are then inspected for:
A typical production setup may include:
The exact configuration depends on product size, design complexity, number of colors and production capacity.
For multi-color products, a PVC Keychain Automatic Dispenser can automate the dispensing stage and improve production consistency.
Multi-color PVC products require accurate positioning to maintain clear boundaries between different colors and layers.
Poor dispensing accuracy can cause color misalignment, material overflow, inconsistent product appearance and increased material waste.
High-precision 3D Keychain PVC Dispensing Machines use programmed motion control to repeatedly position the dispensing head according to the production file. For detailed logos, cartoon patterns and customized products, ±0.01 mm repeat positioning accuracy can help improve manufacturing consistency.
Zhenying Machines specializes in automated PVC and silicone processing equipment.
In addition to Dispensing Machines, the company can provide a one-stop manufacturing solution including:
The Multi Color 3D Toys PVC Dispenser Machine can be configured according to product size, color requirements and production capacity, supporting the automated production of PVC keychains, toys, labels and other soft PVC products.
They are typically produced through design, mold preparation, PVC dispensing, heating, layer-by-layer forming, cooling and finishing.
A typical production setup includes a PVC Dispensing Machine, customized molds and heating equipment.
Different PVC colors are automatically or manually dispensed into designated mold areas. The product is then formed through repeated dispensing and heating stages.
Yes. Automatic dispensing equipment can control dispensing paths and material volume, helping improve repeatability and production efficiency.
