Sumitomo Injection Molding Machine Maintenance Special | The Importance and Confirmation Methods of Machine Level

Sumitomo injection molding machines are the core foundation for ensuring equipment stability and product qualification in high-speed and high-precision production. The horizontal deviation may seem small, but it can causemoldA series of issues such as wear and tear, product defects, and equipment wear and tear.

The high precision of Sumitomo injection molding machines comes from the dual guarantee of strict factory processes and on-site level calibration.

A qualified machine level is a prerequisite for all precision adjustments. When assembling a new machine, the level must be calibrated first before completing the following core accuracies:

1linear guideSliding accuracy

2Verticality of the template

3Centrality between dynamic templates

4Parallelism between dynamic and fixed templates

5Balance of tensile force of four Corinthian columns

If the horizontal deviation of the machine is too large, all the above accuracies will be affected. Over time, mechanical wear and tear cannot be avoided.

If the machine level does not meet the standard, it will cause irreversible losses from three aspects: product, mold, and equipment

1Shorten mold life, accelerate mold wear and deformation

2The product has defects such as burrs, flow marks, and dimensional eccentricity

3Increased vibration and significant abnormal noise during equipment operation

4Accelerated wear of curved arm copper sleeve, guide rod and other components

5After the wear of the curved arm, further damage is caused to the ball screw of the opening and closing mold

1. Regular inspections;

2. New machine installation, equipment relocation, relocation, or accidental lifting;

3. Discovering significant equipment vibration, ground subsidence or cracks, suspended or damaged foundations, and loose bolts;

4. After eliminating mold problems, there are still abnormal noises, product flying edges, and eccentricity when opening and closing the mold;

When the above situation occurs, it is recommended that Sumitomo after-sales service engineers come to the site for professional level adjustment.

The Sumitomo injection molding machine manual clearly requires that the machine level be checked quarterly

1. Standing accuracy of 0.05mm/mlevel gaugePlease refer to the installation procedure in Chapter 1 of the instruction manual for the measurement method

2. Check the horizontal deviation on a quarterly basis and record the data

When the horizontal offset is too large, it needs to be adjusted to within the range in a timely manner.

4. The correct horizontal adjustment points for the machine are as follows

1Elbow support

2Movable template

3Fixed template

Non professionals are prohibited from adjusting the level of the machine at will

Non professional debugging can exacerbate horizontal deviation and damage core components such as guide rails, drive units, and Corinthian columns

Professional after-sales use of high-precision instruments, calibrated according to original factory standards to ensure balanced force distribution of equipment
