We believe , the only way to go forward, is to strive on Quality, Quality Product along with Quality Packaging & timely Delivery.

In quality front, we try to procure the best grades of every raw material available. All fresh batches are checked for Tensile, Elongation, Hardness and Bursting Pressure before putting into production. Randoms checks are done on the production floor to remove any human error or deviation from the standards. Strict measures are taken to control the prescribed wall thickness of the hose, no. of reinforcement yarn coverage per inch and the finish.

Once the Hoses are manufactured, they undergoes three screening processes, where they are thoroughly checked, before passing on to the packaging department.

We also have our own research laboratory & we are also linked with few big research laboratories, and automobile workshops, where the products are first tested under variety of simulated conditions as well as in real life in automobile workshops, before being introduced in the market.

Today, We manufacture over 1700 different hoses and all are readily available; we believe timely delivery is as important as the quality.

We are also focusing on product range, new products are been introduced every fortnight with an idea to cover complete automobile, and tractor range in India and to make a mark in the international circuit.

We also undertake Customized EPDM Hoses queries, where the compounding can be altered as per the customer specifications which include, specific gravity, temperature & pressure requirement, costing, and material thickness.

All hoses we manufacture matches SAE-J20R4 and AS:420:81:Mar:2014 Specifications.

 

A Specific Gravity Gauge measures the density of rubber (ratio of weight to volume).
It is a simple but extremely important QC tool for rubber compound quality.

1. Ensures Correct Compound Formulation

Each rubber compound has a specific expected density range depending on:

• Polymer type (EPDM, NBR)

• Carbon black loading

• Oil content

• Fillers (CaCO₃, silica)

If density goes outside the target range, it means:

✔ Over/under filler addition
✔ Wrong oil percentage
✔ Wrong batch mix
✔ Material contamination

Benefit:
Prevents defective hoses due to wrong compound formulation.

---

2. Quick and Easy Incoming Raw Material Check

Before using new material lots, SG testing helps detect:

✔ Lower-quality polymer
✔ Change in carbon black grade
✔ Moisture–filled fillers
✔ Cheap filler adulteration

Benefit:
Avoids bad material entering production.

---

3. Detects Mixing Issues During Compounding

During mixing in Banbury or kneader:

• Under-mixed or over-mixed compounds

• Poor dispersion of carbon black

• Oil not absorbed properly

• Wrong ingredient addition

These issues immediately show up in SG test.

Benefit:
Gives fast feedback to correct mixing parameters.

---

4. Helps Maintain Batch-to-Batch Consistency

For hose manufacturing, consistency is essential for:

• Tensile strength

• Elongation

• Burst pressure

• Adhesion

• Ozone resistance

Specific gravity checks ensure every batch remains uniform.

Benefit:
Improves product repeatability & reliability.

---

5. Strong Indicator of Filler Loading

Density directly correlates with:

• Carbon black percentage

• CaCO₃ or silica level

• Oil plasticizer level

Sudden change = possible tampering or mixing mistake.

Benefit:
Prevents low-strength hoses due to excess filler or low reinforcement.

---

6. Quality Control Before Extrusion

Before rubber goes to extrusion line for hose production:

SG testing ensures:

• Compound is within acceptable density

• Wall thickness will remain uniform during extrusion

• No underweight or overweight issues

• Correct swelling/flow behaviour during extrusion

Benefit:
Ensures smooth extrusion & consistent hose dimensions.

A Bursting Pressure Test Pump is a hydraulic test system used to check the maximum pressure a hose can withstand before it fails (bursts).
It is one of the most critical tests for automotive and industrial rubber hoses.

Burst testing can be:

• Static burst test (slowly increasing pressure)

• Proof pressure test

• Impulse/fatigue pressure test (repeated cycling – higher-end equipment)

---

Why Burst Testing Is Essential for Hose Manufacturers

🔸 Ensures Hose Can Handle Real-World Pressure

Radiator, heater, and oil lines face high pressure and temperature cycling.

Burst pressure testing confirms:

✔ Hose will not crack
✔ Hose will not split under pressure
✔ Reinforcement is strong and properly bonded
✔ Hose is safe for the vehicle and customer

🔸 Validates Reinforcement Strength

Reinforcement (Polyester/Nylon) is the MAIN factor behind pressure resistance.

Burst testing checks:

✔ Quality of reinforcement yarn
✔ Correct wrapping/braiding pitch
✔ Proper layer bonding
✔ Correct wall thickness

If reinforcement is weak → hose bursts early.

---

🔸 Detects Manufacturing Defects

The pump helps identify issues such as:

• Thin wall sections

• Poor adhesion between layers

• Improper cure

• Air pockets/voids

• Overloaded filler in rubber

• Yarn slippage or improper wrapping

Benefit: Weak hoses are caught BEFORE dispatch.

A Muffle Furnace is a high-temperature chamber (500–1200°C) used for ash content, filler analysis, and material verification of rubber compounds.

1. Determines Ash Content (Filler Loading)

Rubber compounds contain fillers like:

• Carbon Black

• Calcium Carbonate

• Silica

• Clay

• Zinc Oxide

• Process oils (burn off)

A muffle furnace burns off all organic rubber material, leaving behind pure inorganic ash.

Why this is important:

✔ Ensures correct filler percentage
✔ Detects if excessive CaCO₃ or cheap fillers were added
✔ Maintains strength, burst pressure & durability
✔ Confirms compound formulation accuracy

---

2. Helps Maintain Consistency of Rubber Compound

If compound density or tensile properties suddenly change, the muffle furnace helps identify why.

Changes in ash content indicate:

✔ Mixing error
✔ Wrong ingredient addition
✔ Supplier batch variation
✔ Poor dispersion

This ensures every batch meets standard performance.

---

3. Detects Rubber Adulteration or Material Mixing Issues

In some cases, suppliers may mix:

• Lower-grade carbon black

• Excess CaCO₃

• Recycled rubber powder

• Unplanned fillers

Muffle furnace testing easily detects this.

Benefit:
Prevents weak hoses and burst failures.

 

4. Essential for R&D and Compound Development

In new compound development, muffle furnace helps in:

✔ Optimizing filler loading
✔ Controlling cost without reducing strength
✔ Comparing carbon black grades
✔ Balancing hardness vs flexibility
✔ Improving heat & oil resistance

This directly improves our hose performance & cost efficiency.

---

5. Helps Investigate Field Failures

If a hose fails during customer use, ash analysis reveals:

✔ Was filler too high?
✔ Was the wrong compound used?
✔ Was there rubber contamination?
✔ Did heat aging alter composition?

This helps improve quality and prevent repeat failures.
