Platen maintenance of die casting machines is an important part of ensuring the normal operation and longevity of equipment.
In the aluminum die casting industry, the performance and longevity of your machines play a crucial role in ensuring consistent quality and operational efficiency.
One of the most critical in HPDC—but often overlooked—components in this process is the platen.
The platen holds and aligns the die halves, bearing immense pressure during each cycle. Over time, due to repeated stress and thermal exposure, the platen can suffer from cracks, warping, or wear.
If left unchecked, this can lead to poor die alignment, flash issues, increased maintenance costs, and ultimately premature machine failure.
At Haichen Machinery, we understand the importance of every component in the die casting process.
We support industries by providing technical guidance and high-quality services related to platen repair and machine maintenance, helping you reduce costs and increase productivity.
Why Platen Repair Matters？
- Extends Machine Life
- Improves Die Alignment and Part Quality
- Reduces Downtime
- Cost Efficiency
- Sustainability
Extends Machine Life
Timely platen repair helps restore its structural integrity, ensuring the machine can continue operating without the need for early replacement.
Improves Die Alignment and Part Quality
A damaged platen can cause die misalignment, affecting casting accuracy. Repairing the platen ensures tighter tolerances and more consistent parts.
Reduces Downtime
Preventive maintenance and repair reduce the frequency of unexpected machine stoppages, saving valuable production time.
Cost Efficiency
Repairing a platen is significantly more economical than replacing it—or worse, dealing with total machine failure.
Sustainability
Regular platen refurbishment supports sustainability by reducing waste and extending the lifecycle of existing equipment.
Regular cleaning and maintenance
Platen and related components can lead to uneven surfaces.
If they are corroded, which increases preparation time and affects product quality.
Therefore, regular cleaning and maintenance is an effective way to reduce preparation time and improve product quality.
Minor Maintenance and Major Maintenance
Typically, minor maintenance of the die casting machine is the responsibility of the die-casting factory.
While major repairs and replacements are the responsibility of the purchaser.
Minor maintenance includes “run-to-run” maintenance of usable molds to maintain die casting production.
Major maintenance involves replacing or rebuilding important components.
Such as entire mold cavities, mold sections, complex core sliders, tool steels, coatings, or major mold finishes.
Surface treatment
In order to prolong the service life of the mold tool, it is necessary to carry out sandblasting and grinding on the surface of the tool.
These treatments can reduce wear and tear, which in turn extends the life of the mold.
Safety measures
Care must be taken when installing and operating the platen to prevent accidental injury.
For example, when installing bolts, it is necessary to support the pressure plate with both hands to prevent injury from falling.
Preventive maintenance
Regularly monitor the status of machines and tools to eliminate potential failures and damage in advance.
This type of maintenance is usually carried out during shifts with reduced production.
Use of original parts
When replacing worn parts, use original parts.
And use oil and grease as recommended by the manufacturer to ensure the functionality and safety level of the equipment.
Through the above measures, the pressing plate of the die casting machine can be effectively maintained.
And ensuring its long-term stable operation, and improving production efficiency and product quality.
Surface of platen maintenance of die–casting machine
Proper maintenance of the surface of the die casting machine’s platen can extend its service life, and Haichen will use the following methods:
- Powder coating
- Baking paint
- Oil injection
- Oxidation treatment
- Sandblasting
- Electroplating
- Vibration grinding and polishing
- Correction
- Manual work
Powder coating
This is a process in which powder coating is evenly sprayed on the surface of aluminum alloy die castings by electrostatic spraying machine.
Under the action of electrostatics, the powder adheres to the surface of the workpiece, forming a uniform coating.
This method results in a long-lasting, uniform finish.
Baking paint
Baking paint is a method of curing coatings by high temperatures.
It can improve the corrosion resistance and aesthetics of die castings.
Oil injection
Oil injection is a method of spraying oil mist onto the surface of the workpiece under high pressure, which can improve the lubricity and corrosion resistance of die castings.
Oxidation treatment
Oxidation treatment is a method of forming an oxide film on the surface of the workpiece through chemical reaction.
It can improve the corrosion resistance and wear resistance of die castings.
Sandblasting
Sandblasting is a method of removing impurities and burrs on the surface of a workpiece by blasting sand particles at high speed, which can improve the surface finish of die castings.
Electroplating
Electroplating is a method of forming a metal coating on the surface of a workpiece through an electrochemical reaction, which can improve the corrosion resistance and wear resistance of die castings.
Vibration grinding and polishing
Using vibration grinder, centrifugal polishing machine and other equipment, the use of grinding stone, abrasive, water, etc.
In the process of high-speed vibration (rotation) friction with the die-casting to achieve the effect of removing burrs and polishing the surface.
Correction
When a die casting is deformed due to solidification shrinkage, ejection deformation, or cutting edge deformation, it needs to be corrected.
Manual work
Utilize simple tools such as mallets, files, pliers, etc., to remove excess parts such as casting pouring systems.
Cleaning and degreasing
Use equipment such as vibrators and belt grinding machines to grind, deburr, shot blast and sandblast the surface of die castings.
Then, the grease is degreased by spraying at room temperature to remove the grease on the surface of the blank.
Haichen Platen maintenance advice
Haichen reminds you that when carrying out high-pressure water cleaning operations, you must strictly follow the safety operation procedures.
And wear necessary protective equipment, such as protective glasses, gloves, etc., to prevent high-pressure water flow from causing injury to operators.
Before the operation, it is necessary to complete the equipment inspection according to the inspection table.
And understand the status of the equipment, and make corresponding records.
Check the status of the water and air channels to ensure that the air pressure is normal.
And the valves are in the correct position.
During the mold cooking process, waste lye and cleaning wastewater are generated.
Therefore, these wastewater require proper treatment to avoid environmental pollution.
Additionally, if operators find any unsafe situation, they should stop the operation immediately and then report it to the relevant person in charge or safety supervisor promptly.
Haichen‘s after-sales support
Haichen’s requirements for after-sales service are that when customers encounter technical issues.
They should respond promptly upon receiving the notification and solve the problem within 2 hours.
In some cases, online technical support is required to respond 24/7.
And Haichen also offers offline technical support, which can meet the requirements of customers as needed.
