We manufacture molds with different shot lives tailored to your project’s various stages, helping you effectively control mold costs.

Insert molding is an advanced injection molding process where pre-placed functional inserts (such as metal pins, threaded fasteners, PCBs, or magnets) are encapsulated with molten plastic to form a single integrated part.

To adjust the injection molding process.First,check the amount of pressure being used to press the two halves of the mold together which is typically measured in tonnage.

If not enough force is being applied to each half of the mold the melted plastic can more easily find its way outside of the mold cavity.Increasing the clamping force may be the easiest way to eliminate flash but sometimes the material is too fluid meaning the melt or mold temperature can be lowered to improve the material flow.Flash can simply be caused by a low-quality or worn-down mold that no longer fits well at the parting line.

Sink marks are a localized indentation or depression that appears on the surface of an injection molded part after cooling.

The most common are lowering the mold temperature since an overheated mold can increase uneven cooling.You can also increase the hold pressure,increase the hold time,can if process alterations don`t help it may be necessary to adjust the part design and reduce the thickness of certain sections to promote more even cooling and lower the likelihood of a sink mark.

A burn mark specifically is the result of overheated material which is especially noticeable on white or clear components.

Burn marks can be addressed by altering the injection molding process and adjusting variables like the injection speed,lowering the mold temperature,improving mold venting,and properly cleaning and properly cleaning and maintaining the mold to ensure that material does not become trapped and burn.

This simply refers to an incomplete part where the melted plastic is not fully filling the mold cavity.

In smaller parts,short shots are often the result of a material with a high viscosity meaning it does not flow easily especially into hard-to-reach areas.

You can consider increasing the melt temperature to allow the material to flow more easily or try an entirely different resin with a lower viscosity.

Short shots may also be caused by inadequate venting in the mold which can trap air pockets,a frozen flow channel that may need to be cleaned,or simply not packing enough resin into the mold cavity during injection.

Flow lines appear as a wavy pattern often of a slightly different color than the surrounding area and generally in a narrow section of the molded component.

Flow lines are caused when the liquid plastic solidifies at different rates.

There are many ways to fix them such as increasing temperature raising injection speed changing the type of plastic or changing the product design.
