How to degrease mechanical parts?

The degreasing of metal components, machinery and surfaces is an essential part of a wide variety of industrial and manufacturing activities. Machines must be clean to operate efficiently. Old parts must be cleaned before repair. Items produced should be cleaned prior to finishing, packaging and shipping.

Why clean grease from parts?

The challenges of degreasing mechanical parts vary depending on where the grease accumulates: in your machines, tools and equipment, or on the products you manufacture.

While regular lubrication of parts is generally a good thing, a buildup of dirty grease on industrial equipment can reduce performance and increase the rate at which components wear. And it will increase your production cost.

The risk of grease accumulating on items during production and manufacturing is slightly different. If you don’t remove it correctly at the right points in the process, you risk causing problems in the later stages of production and finishing, especially if they involve coating and painting. Grease can also complicate quality control, whether you do it manually or automatically.

How to degrease parts effectively?

In many cases, the process followed by companies to eliminate fat is long, repetitive and very laborious:

  • Wipe off most of the grease
  • Apply detergent or solvent to dissolve grease
  • Scrub to remove accumulated grease from corners and holes in parts
  • Rinse the surface
  • Dry the parts completely to reduce the risk of rusting
  • And even if you follow this process carefully, there is a risk that the end results will vary from one cleaned part to another.

There is a better way.

Degreasing solutions

The process is similar to the dishwasher you might have in your kitchen:

  • You load dirty items into the machine
  • You select the cleaning cycle you want to run
  • You press Start

The machine cleans mechanical parts, removing grease to a standardized standard that suits you, in a predictable period of time. And while the machine is running, you can focus on other key tasks.

This approach uses modern chemical degreasing solutions that are water-based rather than flammable solvent-based, reducing both workplace hazards and environmental impact. These degreasing fluids are recycled multiple times to minimize costs and include anti-corrosion agents that prevent flash rusting when the cleaned parts dry out.

The Importance of Industrial Mold Cleaning for Productivity and Quality

In a society marked by accelerated industrialization, mass production of standardized products has become the norm.

As such, the key tools are industrial molds, which are used in many processes such as injection molding, compression molding or hot molding. This equipment has a huge impact on the quality and efficiency of production and careful and constant maintenance becomes necessary.

What is an industrial mold?

Industrial molds are tools for giving a precise shape (intermediate or final) to the part or material to be machined, by inserting it in plastic, molten or solid form inside 2 half-molds, the one fixed and the other mobile, in order to determine the shape to be obtained.

Generally made of steel, but also aluminum for prototyping activities, industrial molds have a lifespan that can range from a few parts (even just one) to hundreds of thousands of parts.

When a mold is destined to shape thousands of pieces, constant maintenance over time becomes a fundamental activity in order to guarantee the best production quality, avoid sudden production stoppages and ensure the durability of the mould.

The real cost of an industrial mold

An unmaintained industrial mold can generate major costs for a company: costs related to the downtime necessary to carry out maintenance and repair operations (often carried out by mold makers outside the organization), costs generated by the subsequent restart of production and consequent regulation, loss of profits caused by non-optimized production, an increase in the number of nonconforming batches due to poor quality or even, costs arising from the degradation of the long-term corporate image.

Preventive maintenance then becomes a strategic operation for companies and must be favored within the framework of dedicated processes, scheduled regularly. This need becomes even more frequent in the case of aluminum molds or complex relief molds that wear out more easily. The temperature, type of material and the pressure it is subjected to when inserted into the mold can also impact the frequency of maintenance activities.

The correct use of a mold will limit the need for inspection and revision operations, but will not completely exclude them.

And as with any maintenance process, cleaning is a crucial step.

The industrial mold cleaning process

In order to carry out maintenance, the mold must first be dismantled and checked before moving on to the cleaning phase: parts with a higher concentration of dirt or parts with cracks (cracks) must be cleaned. further control to identify defects in the mold to be rectified.

At this point, it is possible to move on to washing operations to remove different types of residue, including:

  • the release agents used to facilitate the extraction of the parts produced, the residues of lubricating oils and the traces left by the gases generated by the contact between the plastic material in the fluid state and the mold at high temperature, which contain residues that soil the mold itself;
  • oils used in the cold forging of metals;
  • residues of soft metals and lubricating oils used to avoid “tearing” in cutting and thus obtain clean cuts;
  • graphite greases used as a mold release agent in the hot stamping of metals.

The cleaning activity must be carried out avoiding damage to the mould; operations such as sandblasting, shot-blasting or the use of aggressive and potentially corrosive products such as caustic soda should therefore be eliminated.

Moreover, reliance on manual washing processes with rags and solvents leads to unsatisfactory levels of cleaning, especially in the case of molds with complex geometries and small figures.

Considering the considerable impact of an industrial mold on the quality of a mass production, it is advisable to carry out a standardized washing always using the same products and methods in order to minimize the possible variability of the characteristics of the production parts.
