The human body is full of filters; air conditioners have filters too, and we even filter tap water. Like everything, our cars have filters, too; the most crucial is the oil filter.
You see the Oil Filter being replaced during your car’s service. But have you ever wondered how it’s made? Watch the video and take a factory tour to understand the process of manufacturing oil filters.

This article will outline the stages, from when the steel sheet is forged to when the finished product is packed into boxes.
Stamping Various Metallic Parts
The stamping process involves the following:
- Steel sheet blanking.
- Extraction of the outer casing.
- Stamping of the base plate and the end cap of the filter element.
Most of the metallic parts of the filter are made at this stage of the filter-making process. The oil filter covering is made out of a circular steel sheet stamped 1-2 times, depending on the size and requirements of the product.
Tapping Base Plate & Making Centre Tube
The base plate is comprised of a tapping plate and a retainer plate. After stamping, the base plate needs to be threaded. This is done in the automated threading machine, after which it’s welded with the retainer plate.
Manufacturing the centre tube starts with cutting the sheet metal into the specified size. Afterwards, another machine perforates the steel sheets and rolls them into tubes. The centre tubes are ready for the next stage of the filter-making process, where they will be inserted into the pleated paper core.
Making The Element
The filter element-making involves preparing the paper for pleating and assembling the element. It consists of the following steps. The centre tube is put in the paper core; the element is ready for the oil filter, which will filter all the contaminants.
Final Assembly
First, a worker puts the base plate into the assembly line, loads the anti-drain back valve into the base plate, and then positions the filter element on the base plate. The worker then puts the support spring on the filter element core and the outer bowl on the filter assembly. The filter edges are folded down to form a rim using a seamer machine.
After fabricating the oil filter, the sampled product is packaged for delivery to the customer. This filter is ready to do the work of cleaning the oil circulating through your car’s engine. Meanwhile, back at the factory, manufacturing more filters continues.
