1. Purpose: To ensure that the equipment can maintain the best performance state and extend the service life to ensure the normal production.


1. This standard must be implemented by trained injection moulding technicians and mould managers.

2. The injection moulding foreman is responsible for implementation and inspection and supervision, and is in charge of regular supervision.

Maintenance of Furniture Mould(FURNITUREMOULD) before production

1. The surface oil and rust of the furniture mould must be cleaned up. Check the cooling water hole of the furniture mould for foreign matter. Is there any waterway?

2. It is necessary to check whether the arc in the rubber mould cover of the furniture is damaged or not, and whether there is any foreign matter remaining.

3. Whether the screws and the clamping clips of the fixed template of the furniture mould are tightened.

4. After the furniture mould is installed on the injection machine, the empty mould must be operated first. Observe whether the operation of each part is flexible, whether there is abnormal phenomenon, whether the active part such as the guide post, the ejector pin, the row position is worn, whether the lubrication is good, the ejection stroke, the opening stroke is in place, and whether the parting surface is in conformity when the mould is closed Strictly wait.

Quarterly routine inspections:

Mainly for the cleaning and maintenance of furniture mould that have not been used for more than two months.

1. Open the furniture mould and check the internal anti-rust effect. If there is any abnormality, it must be re-rustproofed. Long-term use of furniture mould to be buttering.

2. Put it back in place and make a note.

Storage of furniture mould

A mould library should be set up, special personnel should be set up, and furniture mould files should be established. If possible, computer management should be carried out on the moulds. The mould library should choose a place with low moisture and ventilation. The temperature should be kept below 70%. If the humidity exceeds 70%, the mould will be easy to rust. The furniture mould should be stored on the shelf, pay attention to anti-corrosion and dustproof.

In the test mode of the Table Mould(FURNITUREMOULD), you need to pay attention to the following points:

1. To achieve the end of filling, the plastic requires a total pressure of 2200 psi.

2. In order to reach the middle part of the product, the plastic requires a total pressure of 2200 psi.

Based on the above two points, the process is limited by pressure.

The plastic requires a pressure of 1379-983 = 396 psi to reach the end of the third splitter from the end of the secondary splitter. In order to flow through the gate, the plastic requires a pressure of 1897-1379 = 518 psi.

Therefore, the three-stage flow passage and the gate seem to have a relatively large pressure drop, so the three-stage flow passage and the gate should be enlarged. This will reduce the final pressure at the end of the fill to 1901 psi. This process is no longer limited by pressure. Ensuring adequate injection pressure helps achieve consistent table mould filling. Pressure drop research is one of the most important steps in the table mould certification process.

Finally, remember the rule of thumb: The maximum injection pressure required should not exceed 80% of the maximum pressure available to the injection moulding machine.

Values above 80% should be lower for thicker products that require higher holding pressure. To avoid sudden increases in pressure between different components, the transition should be as smooth as possible.

1. If the cavity is poorly processed, if there are defects such as scratches, micropores, abrasion, roughness, etc., it will inevitably be reflected on the plastic parts, and the gloss of the plastic parts is poor. In this case, the Air Cooler Mould(FURNITUREMOULD) should be carefully machined to make the cavity surface rougher and chrome-polished if necessary.

2. If the surface of the cavity is oily or watery, or if there are too many release agents, the surface of the plastic part will become darker and darker. To do this, remove grease and water stains in a timely manner and use a limited amount of release agent.

3. If the plastic parts are too small, the demoulding is difficult, or the force is too large when demolding, so that the surface gloss of the plastic parts is good. In this case, the draft angle should be increased.

4. If the air cooler mould is depleted, excess air will be left in the air cooler mould, which will also result in reduced gloss. To do this, check and correct the air cooler mould exhaust system.

5. If the cross-sectional area of the gate or runner is too small or abruptly changed, the shear force is too great when the melt flows therein, and the turbulence is dynamic, resulting in poor gloss. To this end, the cross-sectional area of ??the gate and runner should be properly enlarged.

The heat treatment of steel moulds is an important means of hardness. Generally, after the rough opening of the Daily Necessities Mould(FURNITUREMOULD), the moulds are returned for finishing. The heat treatment during the processing will also be risky. Improper handling will cause cracks in the steel and scrap, resulting in abnormalities. The reasons for plastic steel materials are:

1. Daily necessities mould materials have severe network carbide segregation.

2. There are mechanical or cold plastic stresses in the daily necessities mould.

3. Daily necessities mould heat treatment is improper (heating or cooling rate is too fast, quenching medium is not properly selected, cooling temperature is too low, cooling time is too long, etc.).

4. Daily necessities mould has complex shapes, uneven thickness, sharp corners and fine threaded holes, which keep thermal stress and tissue stress too large.

5. Daily necessities mould the heating temperature of the mould quenching is too high to cause overheating or overheating.

6. When hardened, the tempering is not timely or the tempering time is insufficient.

7. When the daily necessities mould are reworked, quench heat without intermediate annealing.

8. Dirty grinding process for daily necessities mould heat treatment.

9. High tensile stress and microcracks in the hardened layer after heat treatment of the daily necessities mould.

After a long period of development, the Furniture Mould(FURNITUREMOULD) industry is currently in a rising period. At this stage, what kind of development method should the furniture mould company adopt? It has become a problem that major mould companies are actively thinking about. Long-term price wars are gradually accepted by enterprises, and technological competition is gradually emerging.

The domestic furniture mould industry is at the low end of the world furniture mould industry. This situation is related to the low level of technology and ongoing price wars across the industry. In order to develop, the furniture mould industry must continuously increase research and development funds, increase the technological content, and produce products with core competitiveness. Strengthening product research and development efforts can really change the current competition model.

Why is the domestic furniture mould industry always playing a price war? There are many enterprises engaged in the production of furniture mould in China, but the scale is relatively small, basically all of them are small workshop models, and the technical content is very low.

The products produced by the small furniture mould company are basically imitated, resulting in more and more uniform middle and low-grade moulds. Furniture mould companies are facing the problem of overcapacity and inventory backlog.

In order to increase sales, furniture mould companies will lower the price of their products. Several furniture and mould companies have cut prices, which eventually led to the whole industry being in trouble and the profits of enterprises are becoming less and less. When profits continue to shrink, the company has no additional funds for product development.

Long-term price wars within the industry will affect the entire industry. China's furniture mold companies should increase the technical content of their products, from the current price war to the technical competition.

From now on, it is only necessary to seize market share rather than profit, and become a common market to make a profit. It is believed that after the transformation of the competition model, the production level of the enterprise can be greatly improved, effectively combating vicious competition and bringing the furniture mold industry to a higher level.

1. Easy to process and maintain.

Furniture Mould(FURNITUREMOULD) is a very complicated part. During the processing, they often encounter some complicated structures and special shapes. These shapes are difficult to process and difficult to maintain. For these structures, it can be used to reduce the difficulty of processing and maintenance.

2. Easy to shape and mould.

If the product has deeper ribs or other unformed structures, these structures are prone to under moulding, scorching and other defects. It can effectively solve this problem, the gap between the furniture mould inserts can not only facilitate the exhaust of the furniture mould, but also prevent the vacuum adhesion phenomenon when the product is demolded.

3. Improve the strength of furniture mould.

In the cavity or the slider of the cavity part, it is broken or broken in a small area. In order to increase the strength of the furniture mould and improve the life of the furniture mould, the plug can be broken (or broken) and the material can be replaced.

4. Save materials and reduce costs.

When there are cavities or sliders on the furniture mould parts, when other surface parts have many shapes or are used for processing, the furniture mould inserts can be torn to save materials and reduce processing cost, otherwise the material size will increase and the processing time is low. There will be a lot of waste in costs.
