Injection Molding for Plastic Optical Products

What is Injection Molding?

In the plastic mold industry, injection molding for plastic optical products is defined as a crucial plastic processing technique that involves heating plastic raw materials (typically in granular or powdered form) to a molten state within an injection molding machine. Under high pressure, this molten plastic is then injected into a pre-designed mold. As the plastic cools and solidifies within the mold, it takes on the specific shape and dimensions of the mold cavity. Once the process is complete, the mold opens, and the formed plastic product is ejected or removed for subsequent handling (such as trimming, assembly, etc.), ultimately becoming a finished product.

What is the Process of Injection Molding ?

● Raw Material Preparation: Selecting the appropriate plastic raw material and performing preliminary treatments like drying and mixing.

● Heating and Melting: Feeding the plastic raw material into the injection molding machine's barrel, where it is heated and sheared by the screw to melt into a viscous and flowable melt.

● Injection Molding: Injecting the molten plastic under high pressure through the nozzle of the injection molding machine and into the mold cavity via the gate system.

● Cooling and Solidification: Allowing the plastic to cool and solidify within the mold, acquiring the desired shape and dimensions.

● Ejection: Opening the mold and ejecting or removing the formed plastic product.

● Post-Processing: Trimming, assembling, inspecting, and other post-processing steps to transform the ejected plastic product into a finished good.

Application :

Optical product injection molding production is widely used in the manufacture of various optical elements and components, such as lenses, prisms, mirrors, filters, etc. These products are widely used in photography, videography, telescopes, microscopes, glasses, car lights, projectors, and other fields.
