Portafilters Built Around Machine Compatibility, Brand Design & Repeat Production
SiF manufactures bottomless, spouted and convertible espresso portafilters for coffee machine brands, distributors, accessory brands and spare-parts suppliers. Standard platforms cover De’Longhi 51mm, Breville / Sage 54mm, E61 58mm and La Marzocco applications, with custom development available for new machine projects.
Start With the Group Head and Locking Geometry
Portafilter compatibility depends on head diameter, ear count, ear geometry, insertion depth and machine-specific locking position — not diameter alone.

3-Ear Platforms
Bottomless, closed and convertible solutions for Dedica-family and related De’Longhi machine platforms.

3-Ear Platforms
Open, closed and 2-in-1 portafilter options for common Breville / Sage 54mm machines.

2-Ear Platforms
Bottomless, double-spout and convertible configurations for E61-style machine groups.

Brand-Specific Geometry
Dedicated portafilter structures can be supplied for La Marzocco-type group configurations where ear geometry differs from generic E61 designs.

New Machine Development
For non-standard machines, we can review a drawing, physical sample or group-head specification before prototype development.
Choose the Product Architecture Before You Customize the Look
Machine fit comes first. Once the head structure is confirmed, handle, spout, logo, finish and packaging can be developed around the product program.

Open / Naked Portafilter
Designed for brands and distributors that want a clean open-head format and broad basket visibility.

Single / Double Spout
Closed portafilter bodies with single- or double-spout structures for traditional machine configurations.

Convertible Portafilter
A differentiated structure that allows one product platform to switch between bottomless and spouted use.
A Portafilter Project Is More Than a Handle and a 58mm Head
For repeat B2B supply, locking geometry, material, machining, joining, surface finish and branding must work together. SiF can coordinate the main manufacturing processes required across the portafilter program.
Head Structure
Bottomless, closed, spouted and convertible body architectures.
Ear Geometry
Ear count, width, thickness, angle and locking position reviewed by platform.
SUS304 Heads
Representative models use stainless-steel head structures for repeat supply.
Machining & Die Casting
Production routes selected based on component geometry and volume.
Handle Systems
ABS, aluminum alloy, rosewood, walnut and other selected handle concepts.
Laser Marking
Brand logos and selected markings can be added for private-label programs.
For Machine Brands and Distribution Businesses
Develop the Portafilter Around Your Group Head
If a standard De’Longhi, Breville, E61 or La Marzocco structure does not fit, SiF can work from your group-head drawing, existing portafilter or target locking geometry.
- Head diameter and depth review
- Ear dimensions and locking angle
- Prototype machining / validation
- Handle and spout interface development
- Repeat-production planning
Build a Portafilter Range That Looks Like Your Brand
Start from proven machine-compatible structures, then differentiate the range through handle material, finish, logo, packaging and product configuration.
- Bottomless / spouted / 2-in-1 options
- Wood and aluminum handle concepts
- Laser logo and private labeling
- Retail-ready custom packaging
- Samples before larger product launches
