Recently, many companies are facing difficulties in selecting upper and lower sandblasting molding machines. As core equipment in a foundry, choosing the right model directly impacts production efficiency and product quality. The following are brief selection recommendations summarized by our Jinli technical engineers:

一、Consider production capacity compatibility

1. Medium-sized machines are ideal for processing automotive parts.

2. Large-sized machines are designed specifically for engineering machinery castings.

二、Energy-saving performance

Newer models generally use variable frequency control technology, reducing energy consumption by 30% compared to older models

Inspect core configurations

Focus on three components:

✓ Is the sandblasting valve an internationally renowned brand?

✓ Does the control system have an automatic diagnostic function?

✓ Does mold switching support fast positioning?

三、Inquire about after-sales service

Quality suppliers should provide:

24-hour remote technical support

A local spare parts warehouse (with at least 5 key components)

At least two free maintenance services per year

四、Calculate overall costs

     For example, when a company purchases a medium-sized machine from Manufacturer A, the equipment costs 150,000 yuan more but uses 20% less electricity, resulting in a savings of 280,000 yuan over a five-year lifespan. 

     Our newly launched third-generation intelligent sandblasting molding machine is already in use at over 50 foundries nationwide. Please schedule an on-site trial (24-hour hotline: +8618520402216).
