Silicone Dripping Dispensing Molding

Dripping Injection Dispensing(co-injection) Molding is a process for making silicone multicolored products.

They allow two different silicone materials (solid silicone rubber and liquid silicone rubber) to be combined into a single product stream. Liquid silicone’s colors can be adjusted according to different customers, and the colors will do nothing to the qualities of liquid silicone. When in use, we need to mix the two parts evenly according to a certain proportion first, and then carry on the vacuum processing.

This specialized process can be used to enhance product color performance and reduce cost without any penalty to cycle time or production volume.

It is widely applied to the more multicolored silicone products. The colors and pattern can get from 2-12 colors and with a different pattern. It will be widely used for licensed products with characters. Especially for the games, IPs/Movies/Animation/ Character’s peripheral cute products.

Jution Silicone Dripping Dispensing Molding process produces custom prototypes and end-use production parts in 10 days or less. We use Copper molds that offer cost-efficient tooling and accelerated manufacturing cycles, and stock various grades and durometers of LSR and Solid silicone materials.

The Dripping Molding Process

This Processing is more complex, we often say the silicone trademark, silicone drip label, etc. Belongs to this kind of drip. Like drip teethers, dripping bibs, dining table mats, car interior decoration, and other series of products.

Air-exhaust by Vacuum

The Liquid Silicone Rubber material is Air-exhaust by Vacuum. Then add the pigment to get the colors that the colors needed.

Program And Dripping The Liquid Silicone Rubber

The Precision Dripping molder programs control the dripping settings.

Twelve dripping heads can work 12 cavities same time and also can work 4 cavities with 3 different colors. One machine can save 4 to 6 workers. And Twelve fast buttons can run 12 different designs same time very easily and fast.

Heat-Cured

Heated the tooling and let the liquid silicone material is heated to solidify it.

Solid silicone material

Adding pigment to the silicone is performed by mixing via a two-mill roll.

Silicone raw material itself is a milk-white or transparent gum-like component with no elasticity and strength. To improve the characteristics of raw silicone material and to have the desired color, silicone material will be compounded with many ingredients such as vulcanizing agent, reinforcing filler,  accelerator, colorant, etc.

Silicone compounding is the complex technology of selecting and blending silicone with other ingredients. The proper mixture is crucial to the success of silicone molding production.

Weigh it and shape it to match the needed size

It then will be cut into slices by an automatic cut machine. The slices’ length and width will be controlled according to the silicone part’s weight to be molded. Silicone blanking makes it easier for our molding operators to weigh the material during silicone molding production.

Co-injection Compression Molding

Put the Solid Silicone Material on the cured Liquid Silicone material on the tooling. Then They put it into the mold cavity for formation, compressing the silicone between the top and bottom plates.

De-mold

When the silicone is fully cured, the vulcanizing molding machine will release the pressure automatically, tool mold will come out and open for molding operators to remove the molded silicone parts. The raw material will be placed again for the next round of vulcanization.

De-Flash

Flash can be minimized with favorable designs and better tooling and accurate material weight during vulcanizer molding production. Flash will be removed mainly by hand, cryogenics deflashing can also be applicated for some cases.

Advantage:

  • Minimal lead time: Short set up a time
  • Easy to prototype: Minimal wastage
  • Widest range of part sizes: Perfect for the manufacturing of parts with a very large cross-section
  • Dimensional stability: Capacity to process stiff, high durometer materials, Excellent for low quantities of parts requiring a long cure time
  • Low tooling and equipment costs: Tooling is simpler and more cost-effective than injection molding, Although this technique has a longer cycle time, it is a low-pressure mold, which means it’s inexpensive to produce a variety of cavities without high tooling costs.
  • High production rates and shorter production cycles (results in lower per unit cost);
  • Allows for close tolerances in small intricate parts;
  • Requires little post-production work because parts have a finished look upon ejection;
  • Full automation is possible, which leads to reduced production costs
  • Design: Multi-colored. You can get 12 colors in one product without any printed.
  • Flexibility: Can make the 3D show with the products.
  • Attraction: More attractive and cute as gifts for the kids and Women

Design: Multi-Material. You can get 2 different material in one products

  • Extrusion molding also comes with its own set of advantages.
  • Continuous process can produce lengths of up to 60 feet;
  • Consistent cross-section results in the production of complex shapes;
  • High production volumes;
  • Low cost per pound of materials used;
  • Good for producing tube-shaped products such as pipes and hoses.
