Rubber Seal Production Line
I. Product Description
This is a complete production line dedicated to manufacturing various rubber seals, including processes like mixing, molding (injection/compression/extrusion), vulcanization, trimming, inspection, and packaging. Purpose: Used to produce various rubber seals such as O-rings, oil seals, gaskets, sealing rings, dust seals, sealing pads, etc., widely used in automotive, aviation, machinery, hydraulics, home appliances, piping, and other fields. They possess properties like sealing, dustproofing, waterproofing, pressure resistance, oil resistance, and temperature resistance.
Main products include: O-rings: For static and dynamic sealing in hydraulic and pneumatic systems.
Oil seals: For sealing rotating shafts, preventing oil leakage. Gaskets / Sealing pads: For flat sealing of flanges, housings, etc. Sealing rings / Dust seals: For construction machinery, valves, cylinders, etc. Special-shaped seals: Complex structural seals customized according to customer drawings. This production line features high precision, high efficiency, and the capability for both small-batch, multi-variety or large-volume production.

VI. Process Flow (Brief Description)
Typical process flow for rubber seals is as follows:
Batching & Mixing: Rubber raw materials and various additives are mixed into compound in internal mixer/open mill.
Molding: The compound is shaped into seal preforms via injection, compression, or extrusion.
Vulcanization: Heated and pressurized in vulcanizer to set shape and impart elasticity and sealing properties.
Trimming: Remove flash, burrs to improve appearance and precision.
Inspection: Dimension, appearance, sealing performance testing.
Packaging: Qualified products packaged and stored.
VII. Application Fields
Automotive: Oil seals, O-rings, gaskets, hydraulic seals.
Aviation: High-temperature, high-pressure, oil-resistant seals.
Industrial: Pump/valve, piping, cylinder, flange seals.
Home Appliances: Washing machine, refrigerator, air conditioner seals.
Hydraulics & Pneumatics: Sealing rings, dust seals, guide rings.
Others: Construction machinery, ships, valves, instruments.
VIII. Energy Saving & Cost Reduction
APEX's purchased electrical control cabinets and motor systems achieve comprehensive energy savings of 5%-60% through integrated technologies like variable frequency speed regulation, intelligent control, and efficient hardware design. The core energy-saving mechanisms are as follows:
1. Variable Frequency Speed Regulation: Dynamically matches load demand (Energy saving contribution: 10%-35%).
2. Intelligent Control System: Multi-dimensional energy efficiency optimization (Energy saving contribution: 5%-15%).
3. Efficient Hardware Design: Reduces basic losses (Energy saving contribution: 3%-10%).
