What is the difference between pressed and laser formed dimple jacket?

The main difference between pressed and laser-formed dimple jackets lies in their manufacturing process, structural characteristics, and performance.

1. Pressed Dimple Jacket

• Manufacturing Process: Two sheets of metal are mechanically pressed together to create dimples at regular intervals. The sheets are then welded around the dimples to create flow channels.

• Appearance: The dimples are more pronounced and evenly spaced.

• Strength: High structural strength due to the pressing process.

• Heat Transfer Efficiency: Good, but not as high as laser-formed dimple jackets.

• Application: Common in larger tanks and vessels where high pressure is not required.

• Cost: More cost-effective compared to laser-formed dimple jackets.

2. Laser-Formed Dimple Jacket

• Manufacturing Process: A high-powered laser is used to weld two thin sheets of metal together in a precise pattern. The sheets are then inflated using hydraulic pressure to form dimples.

• Appearance: More uniform and seamless dimples.

• Strength: Less structural rigidity than pressed dimple jackets but allows for a thinner, lighter jacket.

• Heat Transfer Efficiency: Higher efficiency due to better fluid distribution and surface contact.

• Application: Ideal for high-precision applications, such as in the food, beverage, and pharmaceutical industries.

• Cost: Higher cost due to advanced laser welding technology.

Which One to Choose?

• For large tanks with moderate heating/cooling requirements → Pressed Dimple Jacket (cost-effective and strong).

• For precise temperature control in sensitive industries → Laser-Formed Dimple Jacket (better efficiency and lightweight).
