Also known as DALON sintered filters and frits, these filters have tiny holes that trap very small particles. Discs are often used in laboratories and gas-bubbling applications (sparging). 

They’re made of Bronze / PE or 316L stainless steel for excellent corrosion and abrasion resistance. 

Select Filtering Degree Based on the size of the particles you wish to remove. For example, the particle size of sand is about 80 microns. View more information on reference particle size in microns below:

The manufacturing process of sintered components is certified as ecological, because the material waste is very low, the product is recyclable, and the energy efficiency is good because the material is not molten.

1.RAW MATERIAL / MIXING

Sinter powders can be of pure metal (iron, copper), or alloyed powders (bronze, steel, etc.)mixed with different alloying elements, depending on the composition of the final material (such as graphite, nickel, copper,…), with an organic solid lubricant.

2.TOOLING/COMPACTING

The powder mixture is compacted inside the tooling, which has the negative shape of the final part. The tool is an element of a very high precision, and high durability. The powder is filled into the tool cavity of a mixer by gravity, and  pressure within 200 to 1500 MPa is applied onto it depending on the final density to be achieved. 

3.SINTERING/INSPECTION

Sintering in continuous furnaces, under controlled speed and at an atmosphere with controlled chemical composition by temperatures between 750 and 1300°C depending on the material 

The result of these basic operation is a metallic part with a certain micro-porosity, high dimensional precision, and perfectly functional.

DALON elevated micrometric porosity of filter components is useful for many applications:

 – Filtration of fluids. Porosity is able to retain the solid particles contained in a liquid or gaseous fluid, and also to separate liquid and solid phases. The application sectors are: automotive, marine, aeronautical, rail, industrial machinery, household appliances, heating, water depuration, food industry, chemical and nuclear industry, packaging manufacturing, tobacco pipes and electronic cigarettes, etc.

FAQ:

Q1. What is your terms of packing?
A: Generally, we pack our goods in neutral cartons. If you have legally registered patent, 
we can pack the goods in your branded boxes after getting your authorization letters.

Q4. How about your delivery time?
A: Generally, it will take 25 to 35 days after receiving your advance payment. The specific delivery time depends 
on the items and the quantity of your order. and if the item was non standard, we have to consider extra 10-15days for tooling/mould made.

Q5. Can you produce according to the samples or drawings?
A: Yes, we can produce by your samples or technical drawings. We can build the molds and fixtures.

Q5-1: How about tooling Charge?
A: Tooling charge only charge once when first order, all future orders would not charge again even tooling repair or under maintance.

Q6. What is your sample policy?
A: We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and 
the courier cost.
