This is a stainless steel coffee machine filter basket manufactured by Ranveth. It filters coffee grounds from brewed coffee while allowing solubles and oils to pass through, and it suits espresso machines, drip coffee makers, and commercial brewers. The basket is built from food-contact stainless steel and is available in standard or custom sizes for OEM and ODM programs.
In a coffee filter basket, performance comes from how the stainless steel mesh and the support structure work together. Ranveth uses precision laser etching and electrochemical forming to create holes with an accuracy of ±0.01 mm, and the hole pattern is kept uniform so that flow is even across the entire basket. The edge of each hole is smooth, which reduces the chance of coffee particles catching and blocking the opening. The mesh is then formed into the basket shape with a rim and handle that match the portafilter or brew head.
This pairing of fine hole size and rigid structure controls three things buyers care about: extraction efficiency, flow resistance, and service life. A uniform hole pattern gives repeatable extraction shot after shot. Smooth holes and a clean surface keep flow resistance stable over many cycles. And because the basket is made of stainless steel rather than a soft material, it holds its shape through repeated heating and cleaning. The result is a basket that supports consistent coffee flavor and a long working life in both home and commercial settings.

The basket is designed for equipment where coffee is brewed under pressure or by gravity. Typical applications include home espresso machines, automatic coffee machines, drip coffee makers, capsule coffee machines, and commercial beverage dispensers that serve coffee or coffee-based drinks. Because the basket is made of stainless steel, it can handle the heat and moisture of repeated brewing cycles and is easy to clean.
Ranveth supplies this basket to appliance brands, coffee equipment OEMs, and distributors. If you are developing a new coffee machine model or replacing a existing basket, we can match the diameter, depth, capacity, and hole pattern to your portafilter or brew group.
To quote a custom basket, we need a few practical details from you. Please send:
With these inputs, our team can propose a stainless steel grade and hole configuration, prepare a sample, and provide a quotation. For standard sizes, we can ship samples from existing stock.
Ranveth is a filter manufacturer based in Zhongshan, Guangdong, China, with more than 20 years of experience in filtration products. Our in-house laboratory is CNAS-accredited, which means we can issue test reports for filtration efficiency, dust holding capacity, and resistance. This matters for a coffee filter basket because it lets us verify hole consistency and flow performance before production, so the media and structure you approve are the ones you receive.
Our production base covers 50,000 m², including six cleanrooms with a total of 20,000 m². These controlled spaces are used for cleaning, assembly, and packaging of food-contact products to reduce contamination risk. We are certified to ISO 9001, ISO 14001, and ISO 45001, and we added IATF 16949 in 2024. Products comply with REACH and RoHS, and we can supply compliance documents on request.
We support OEM and ODM projects with custom size, structure, material grade, logo, and packaging. Over the years we have developed more than 1,000 filtration solutions and continue to export to Europe, the United States, Japan, and South Korea. Our automated lines can produce millions of pieces per month, and quality control covers IQC, IPQC, and OQC at every stage.
To move forward, please tell us your device or vehicle model, the size or a drawing, the required flow rate, operating conditions, and quantity. We will review the details and respond with a sample proposal and a quotation. You can reach us through our contact page.
The basket is made of food-contact stainless steel, typically SUS304, with SUS316L available for some models. These materials meet EU LFGB, US FDA, and NSF food-contact standards. They resist corrosion and high temperature, so they do not release harmful substances into the coffee.
We use precision laser etching and electrochemical forming to hold hole accuracy to ±0.01 mm. The hole pattern is uniform and the edges are smooth, which helps prevent coffee particles from sticking and blocking the flow. Each batch is tested in our CNAS-accredited laboratory for flow consistency, hole distribution, and mechanical strength.
This product is a stainless steel filter basket, so the filtering medium is the stainless steel mesh itself with a support structure. It does not contain activated carbon or ion exchange resin. If your coffee machine requires a water filter cartridge, we can discuss a separate product.
Yes. We offer OEM and ODM customisation for diameter, depth, capacity (single, double, or bottomless), hole size (coarse or fine), handle design, and logo laser marking. We can also provide custom packaging. Please send your machine model or a drawing so we can match the fit.
We provide free samples of standard sizes; the customer pays the freight. For custom sizes, there is a tooling or setup charge, which can be credited against a bulk order. Samples come with a test report from our CNAS-accredited laboratory. To get a quote, send us your specifications and quantity.
For standard products, the MOQ is usually 1,000 to 2,000 pieces. For custom OEM products, the MOQ is generally from 5,000 pieces, and new tooling takes about 40 days. Sample lead time is 7 to 10 days, and bulk orders usually ship in 25 to 35 days.
The replacement interval depends on usage and cleaning. In home use, the basket can last for years if cleaned regularly. In commercial settings with heavy daily use, inspect the basket for wear, deformation, or clogged holes and replace it when extraction becomes uneven. We can advise based on your operating conditions.
Our company is certified to ISO 9001, ISO 14001, and ISO 45001, and we added IATF 16949 in 2024. The stainless steel materials meet FDA and LFGB standards. We also hold NSF, US EPA, and Europe BSC1 certifications, and products comply with REACH and RoHS.
