What is Filter injection molding

Filter injection molding is a specialized molding process that uses filters within the injection molding machine to improve product quality and consistency. Typically. Filter injection molding is the same process as insert molding and overmolding; only the substrate is the filter component instead of plastic or metal inserts, but there are still some small differences between them. Filter components are normally soft, and during the filter mold fitting process, you need to check the fitting status very carefully. This will be more complete than insert molding and overmolding.

During the filter injection molding process, we normally use a vertical injection machine instead of a horizontal injection machine because the filter component may be easy to drop off. A vertical injection machine will solve this issue very easily. And it will be easy for the operator to put the filtering nesh into the mold.

Why Use Filter Injection Molding

In some cases that the plastic parts need filtration function, so that need filter molding process,

One of the primary advantages of filter injection molding is to improve the molding product quality. Like overmolding or inert molding, can strength the part quality and reduce the assembly cost. as well as surface finish.

Another advantages of filter injection molding is saving cycle time and increase the production capacity, this is good for the high volume filter plastic parts production requirement.

Of course comparing to the advantages of filtering injection molding, there are some disadvantages as well, for example the initial filter injection mold cost, even you need 100 pcs of filter molded parts you still need to make a mold for that, this is mean cost.

Filter injection molding process

To make filtration injection molding, the molding process is pretty much the same as overmolding. Below, we briefly explain the price of making filter molding.

Part design

First, you need to have a design. You could hire a design company or your plastic molding supplier to make a design for you.

Filter injection mold

Once the part design is finished, you need to find a custom injection molding company to make filter injection molds according to your design. Be sure to find a professional plastic mold company that has rich experience in making filtering injection molds. If you are not sure who has the most experience in this filtering mold, you are welcome to contact us, and we will solve your issues.

Filter injection molding trial

Once the filter injection mold is finished by your supplier, they will first trial the mold to make some filter-molded components and send them to you to check. They may have some issues from the first time, but please ask them to fix all of them and send you a new sample to approve. Once you have the final, high-quality filter-molded components, the filter injection mold can be ready for production.

Filter injection molding production

After you approve the final sample, you can ask your molding supplier to start production, but you need to specify your packing requirements, because this is very important as well. If you do not explain this, maybe your supplier will use simple packing and may damage the goods during transportation. We normally inform our customers what type of packaging will be used. If our customers agree with us or they require special packing, then we will follow the requirements.

Delivery

Once the production is finished, the final step is delivery. We provide worldwide delivery service for our customers. We first quote both air shipment and boat shipment costs to our customers. Once our customers agree with the price, we will ship the goods to their address. If our customers have a better shipment cost, then they will arrange the shipment. But mostly all of our customers are happy with our shipment cost because we do not add any profits to the shipment cost, which means most of our customers have a better shipment cost, and then they will arrange the shipment. But mostly all of our customers are happy with our shipment cost because we do not add any profits to the shipment cost, which means most of our customers have a shipment cost higher than our cost.

Filter Injection molding applications

There are many industries that use filtering molded parts, such as car filtering components, air filter components, and many more.

We develop filtration-molded products according to customer requirements to suit a wide range of industries, which include automotive, medical, home appliances, and many more. We can use thermoplastic materials such as nylon, PP, ABS, etc.

How to make high-quality filter injection molding products

Making filter injection molds is not easy because filtration injection molds are more complex than other types of inset or overmolded molds.

It needs high-precision machining and good mold fitting experience for the fitting area between the overmold and filter.

We are one of the top 10 plastic injection molding companies in China that offer custom injection molding services worldwide. We have rich experience in filter injection mold as well as other custom injection molds such as overmolding, two-shot molding, stack mold, unscrew mold, high-temperature material mold, and so on.

If you have any project in hand that needs professional filter injection molding or another custom mold, feel free to contact us, and we will provide you with the price in 24 hours.
