Flexible Silicone Funnel for Straining, Draining and Controlled Liquid Flow

This perforated silicone filter funnel features a stepped conical structure with multiple filtering zones on the top, side walls and lower section.

The distributed holes allow liquids to pass through while retaining larger particles, making the product suitable for draining, preliminary filtering, liquid transfer and other customized filtration applications.

Unlike rigid plastic or metal components, the flexible silicone body is less likely to crack when dropped or compressed. The funnel dimensions, wall thickness, silicone hardness, perforation diameter, hole distribution and connection structure can all be customized.

We provide OEM and ODM manufacturing services from design evaluation and mold development to sampling and volume production.

الميزات الرئيسية

Stepped Conical Structure

The multi-level conical design provides several areas for customized perforation patterns.

Each section can be designed with a different diameter, wall angle, height and hole arrangement according to the required flow rate and filtration performance.

Custom Perforation Design

The top, side and bottom sections can be produced with different hole sizes and distributions.

Custom perforation options include:

• Small holes for finer preliminary filtration
• Medium holes for general straining
• Larger holes for faster draining
• Different hole sizes in separate filtering zones
• Round, slotted or custom-shaped openings
• Customized hole spacing and quantity

The appropriate design depends on the particle size, liquid viscosity and required flow rate.

مادة سيليكون مرنة

The funnel can be manufactured from different silicone grades and hardness levels.

Soft silicone provides flexibility and convenient storage, while a firmer material can improve structural support and dimensional stability.

The recommended hardness should be selected according to the product size, wall thickness and installation method.

One-Piece Molded Construction

The funnel body and filtering sections are manufactured as one integrated silicone component.

The one-piece structure reduces unnecessary assembly joints and makes the product easier to rinse and maintain.

Rounded Edges

Smooth radii can be incorporated around the edges and transitions to reduce sharp contact points.

Available surface finishes include smooth, matte, fine-textured and other custom molded surfaces.

ألوان مخصصة

The filter funnel can be produced in gray, white, black, blue, green, red or other custom colors.

Color matching is available according to Pantone references or approved physical samples.

Custom Connection Design

The upper or lower section may include a straight insertion area, retaining groove, sealing rib, anti-slip ring or other equipment-specific connection structure.

For equipment-mounted applications, customers should provide accurate mating dimensions and tolerances.

Funnel Dimensions

The overall height, upper diameter, lower diameter, taper angle and individual step dimensions can be customized.

For products installed in a container or machine, please provide the mating inner diameter, outer diameter, insertion depth and tolerance requirements.

Hole Diameter

Hole diameter has a direct effect on both filtration performance and liquid flow.

Smaller holes retain finer particles but may reduce the flow rate. Larger holes increase drainage speed but allow larger particles to pass through.

We recommend providing the following information:

• Approximate particle size
• Liquid type
• Liquid viscosity
• Target flow rate
• Desired filtration result

Hole Quantity and Distribution

The hole quantity and arrangement can be modified according to the filtration area and required drainage speed.

Holes may be concentrated in one section or distributed across several stepped zones.

صلابة السيليكون

A softer silicone is suitable when flexibility or compact storage is required.

A firmer silicone may be more appropriate for larger products or applications requiring better shape retention.

The final hardness should be evaluated together with wall thickness and product dimensions.

سماكة الجدار

Wall thickness can be adjusted to balance flexibility, durability and structural support.

Thicker walls improve stiffness but may reduce flexibility. Thin walls provide easier deformation but require careful structural evaluation.

مطابقة الألوان

Custom colors can be matched according to:

• Pantone references
• عينات الألوان المادية
• عينات المنتجات المتوفرة
• معايير الألوان المعتمدة من العملاء

A pre-production color sample can be prepared when strict color consistency is required.

Connection Structure

Custom connection options include:

• Straight plug-in section
• أخدود التثبيت
• ضلع مانع للتسرب
• Anti-slip ring
• Flanged edge
• الخطوة الداخلية
• Equipment-specific mounting structure

The mating component or equipment drawing should be provided for accurate evaluation.

Molded Logo

Brand names, model numbers, cavity numbers and identification marks can be molded directly into the silicone surface.

Embossed and debossed options are available.

Design Considerations

Particle Size

The required hole diameter should be smaller than the particles that need to be retained.

For materials with irregular particle sizes, a sample filtration test is recommended before mass production.

Liquid Viscosity

High-viscosity liquids generally require larger holes, more filtering area or a steeper funnel angle.

Flow Rate

A larger number of holes can increase the total flow capacity, but the spacing between holes must be sufficient to maintain product strength.

Structural Support

Large silicone funnels may require thicker walls or a higher silicone hardness to prevent excessive deformation during use.

Temperature Requirements

Please provide the normal operating temperature, maximum short-term temperature and cleaning conditions so that a suitable silicone material can be evaluated.

Food-Contact Requirements

For food-contact applications, the required market, material standard, testing method and documentation should be confirmed before tooling and production.
