Silicone Sealant Production Line – Complete Equipment Configuration Guide
Introduction
A single stainless steel vacuum powerful disperser can handle mixing and dispersion, but to produce silicone sealant efficiently and stably at scale, a complete production line is required. This article outlines the full-process equipment configuration from feeding to filling, along with capacity matching references and workshop layout recommendations.
1. Silicone Sealant Production Process Overview

2. Front-End System: Feeding and Metering
2.1 Powder Handling System
Equipment Components:
| Component | Function |
|---|---|
| Powder storage silo | Stores powders such as silica and calcium carbonate (silo or bulk bag frame) |
| Feed station | Small-bag feed station with dust collector to prevent dust emissions |
| Screw conveyor | Transfers powder quantitatively to the disperser |
| Metering system | Load cells or flow meter with ±0.5% accuracy |
Recommendation: For production lines with capacity ≥500 tons/year, a fully automatic pneumatic powder conveying system is recommended to significantly reduce labor costs.
2.2 Liquid Handling System
Equipment Components:
| Component | Function |
|---|---|
| Liquid storage tank | Stores liquids such as 107 gum and silicone oil (typically stainless steel) |
| Transfer pump | Gear pump or diaphragm pump (suitable for high-viscosity liquids) |
| Filter | Inlet filter to prevent impurities from entering |
| Metering system | Mass flow meter or load cells |
Common Configuration: Weighing metering + PLC control, with automatic sequential ingredient addition according to the formulation, achieving accuracy of ±1 kg.
3. Core Equipment: Stainless Steel Vacuum Powerful Disperser
This is the "heart" of the production line. Selection recommendations are as follows:
| Annual Capacity Target | Recommended Size | Batch Output | Batch Time | Daily Capacity (8 hours) |
|---|---|---|---|---|
| 500-1,000 tons | 200L | 150-180 kg | 2-2.5 hours | 600-700 kg |
| 1,000-3,000 tons | 500L | 400-450 kg | 2.5-3 hours | 1.2-1.5 tons |
| 3,000-8,000 tons | 1100L | 800-900 kg | 3-3.5 hours | 2.2-2.5 tons |
| Above 8,000 tons | 2000L/5000L | 1.6-4 tons | 4-5 hours | 3-8 tons |
Core Configuration Requirements:
| Parameter | Requirement |
|---|---|
| Material | SUS304 for product-contact parts |
| Agitation type | Scraper blade + dual disperser discs |
| Vacuum degree | ≤ -0.098 MPa |
| Temperature control | Jacketed cooling (silicone sealant requires temperature ≤40°C) |
Efficiency Improvement Tip: One machine paired with 2-3 movable tanks allows simultaneous production and discharge, increasing equipment utilization by over 50%.
4. Back-End System: Discharge and Filling
4.1 Hydraulic Extruder
Function: Extrudes the high-viscosity paste from the disperser tank into the filling machine.
Key Parameters:
| Parameter | Typical Range |
|---|---|
| Extrusion force | 100-300 tons (depending on tank size) |
| Extrusion speed | Adjustable, 0-500 mm/min |
| Seal type | Piston seal ring (wear-resistant, high-temperature resistant) |
Selection Tip: Verify that the extruder interface matches the disperser tank dimensions. Some suppliers offer a "one-to-two" solution (one extruder serving two dispersers).
4.2 Automatic Filling Machine
Type Selection:
| Filling Type | Applicable Product | Accuracy | Speed |
|---|---|---|---|
| Cartridge filler | 300-500ml cartridges of glass sealant | ±1% | 30-50 pcs/min |
| Sachet filler | 600ml sachets of beauty glue | ±1% | 20-30 bags/min |
| Drum filler | 20-200L drums | ±0.5% | 4-8 drums/min |
Ancillary Equipment:
-
Automatic cartridge/cap feeding device
-
Automatic labeling/coding machine
-
Automatic carton erector and sealer
5. Workshop Layout Recommendations

5.2 Key Design Considerations
| Consideration | Recommendation |
|---|---|
| Material flow | One-way flow to avoid cross-contamination |
| Operating space | Maintain ≥1.5m aisles around equipment |
| Ceiling height | Account for hydraulic lift – minimum clear height 4.5m |
| Utilities | Compressed air, cooling water, vacuum piping, electrical supply |
| Environmental compliance | Dust collector at feed point; centralized treatment of vacuum pump exhaust |
Conclusion
Building a high-cost-performance silicone sealant production line centers on selecting the right disperser, properly configuring front-end and back-end systems, and optimizing workshop layout. From an entry-level configuration for 500 tons/year to large-scale production above 8,000 tons/year, the above solutions can be flexibly adjusted according to actual needs.
