The selection of Chair Mould(FURNITUREMOULD) materials is also important because it not only affects the service life of the chair mould but also directly affects the manufacturing cost of the chair mould. Therefore, some principles should be followed in selecting chair mould materials. Let's take a look below.

(1) According to the type of chair mould processing and its working conditions, the selected materials shall meet the use requirements and shall have higher strength, hardness, wear resistance, impact resistance, fatigue resistance, etc.

(2) selecting materials according to stamping materials and batch production of stamping parts; Meet the processing requirements, should have good processing performance, easy cutting processing, good hardenability, heat treatment deformation is small;

(3) To meet the requirements of the economy, various chair mould parts can be roughly divided into working surface parts, plate parts, shaft parts, sleeve parts, etc. in the processing and manufacturing of chair mould according to the similarity of parts structure and processing process. The processing methods mainly include mechanical processing and special processing. The mechanical processing methods mainly include the cutting processing of various metal cutting machines. Using common and numerical control cutting machines to carry out turning, milling, planing, boring, drilling and grinding processing can complete the processing of most die parts, and then matching with fitter operation can realize the processing and manufacturing of the whole set of dies.

(4) With the continuous improvement of the quality requirements of the chair mould processing, the mould materials with special properties such as high strength, high hardness, and high toughness are appearing continuously and the number of complex profiles and holes is increasing. The traditional mechanical processing methods have been unable to meet the requirements of mould processing. Therefore, the process methods of directly using electric energy, heat energy, light energy, chemical energy, electrochemical energy, acoustic energy, and other special processing have been developed rapidly. At present, the special processing methods mainly based on electrical processing have been widely used in modern mould manufacturing, which is an important supplement to the mechanical processing methods.

There may be a series of situations in the process of Chair Mould(FURNITUREMOULD) processing customization. In fact, one of the phenomena that we have to face is the bending deformation of chair mould processing. So during the whole processing, besides considering the final requirements or installation, we should also consider the performance of chair mould processing and equipment. In this case, we have to consider the fluidity of more chair mould processing. Then why do chair mould processing customization have some bending deformation?

I. Mould

In the process of customizing the chair mould processing, basically if such a situation occurs, it is believed that the door may be located improperly or in insufficient quantity, or the top product may not be located uniformly.

II. Technology

More technical factors will be taken into account when customizing the chair mould processing. For example, it may be considered that the temperature of the machine pipeline is extremely high, or the injection pressure is extremely high, and there are other situations where the injection is too fast. The heat preservation time is relatively long, and the cooling time is also very short.

III. Raw Materials

When all the raw materials are actually processed, they will affect the final cleanliness and lead to the deformation of the whole product.

IV. Product Design

When the chair mould is customized, each product has its own design style in the process of design. For a simple example, different chair mould has different design requirements because they have different requirements during processing.

Through the above content, we should consider the actual situation in the process of processing the chair mould. When bending deformation occurs, it must be adjusted first to a reasonable state for processing.

The application of the Table Mould(FURNITUREMOULD) formwork is different from that of the cold die. The table mould formwork is generally used between 150-200 degrees. In addition to some pressure effects, there is also the effect of temperature on it. Today, Xiaobian gives you a brief introduction of what kind of steel from four angles can meet the requirements of the table mould formwork:

First, it must have certain hardness and wear resistance, so as to ensure that it will not cause some adverse effects due to excessive pressure and friction during use. In addition, it is also necessary to determine the stability of the mould frame size and shape, so that it can be used for a longer period of time. The chemical composition of the steel and the heat treatment hardness will affect its wear resistance, so the hardness of the mould frame can effectively improve its wear resistance.

Second, many mould frames need to be cut during use. In order to avoid damage to the cutting tool and to make it have the better cutting ability, the hardness of the steel used in the formwork must be within an appropriate range.

Third, the selected steel should have good thermal stability, which is beneficial to the processing after quenching and improve the precision of the formwork.

Fourth, it requires better polishing performance. The impurities in the steel should not be too much. There will be no problems such as pitting during polishing to ensure the quality of the mould base.

What kind of Table Mould(FURNITUREMOULD) is a good mould? What we produce can only be considered by customers. For customers, when signing the contract, we mainly consider the following aspects: mould cost, mould production cycle and mould quality.

These three aspects are quite different for different users. For example, for users who develop their own products to provide plastic parts to the market, they may give more consideration to the cost and production cycle of table moulds. For mould users required by the complete machine factory, they may give priority to the production cycle and quality of moulds. For users of matching products supplied to the complete machine at fixed points, they may have a more comprehensive consideration on these three aspects.

For the cost of table mould, the user's requirement must be the lower the better under the premise of meeting the requirement, and the quality of the mould is mainly measured by the following criteria: mould yield, mould life and mould usability, etc. The precision and quality of the mould can also be measured by the precision and quality table of plastic parts, mainly including no surface defects, low surface roughness, bright or dull surface, high assembly dimensional precision, etc. Generally speaking, the quality of the table mould directly affects the quality of the plastic parts and the injection cost of the plastic parts, and the high-quality mould will definitely increase the manufacturing cost of the mould.

1. Check if the plastic material in the barrel is correct and whether it is baked according to the regulations.

2. The cleaning of the material pipe should be thorough, in order to prevent the inferior compound or miscellaneous material from being injected into the Chair Mould(FURNITUREMOULD).

3. Adjust the pressure and the amount of injection to produce a finished product with satisfactory appearance.

4. Be patient and wait until the conditions of the machine and chair mould are stable.

5. The advancement time of the screw should not be shorter than the time when the plastic of the gate is solidified, otherwise, the weight of the finished product will decrease and the performance of the finished product will be damaged.

6. Run the newly transferred conditions for at least 30 minutes to stabilize, and then at least continuously produce a dozen full-mode samples, mark the date and quantity on the holder, and place them separately according to the cavity to test the stability of the operation. And derive reasonable control tolerances.

7. Compare the dimensions of each chair mould sample. Note:

(a) Whether the size is stable.

(b) Is there a tendency for certain dimensions to increase or decrease to indicate that machine processing conditions are still changing, such as poor temperature control or oil pressure control.

(c) Whether the change in size is within the tolerance range.

8. If the finished product size does not change and the processing conditions are normal, it is necessary to observe whether the quality of each finished product of the cavity is acceptable, and the size can be within the tolerance. Make a note of the number of holes that are continuous or large or smaller than the average to check if the size of the chair mould is correct.

At present, the mould temperature is often neglected during the test of the factory, and the temperature of the chair mould is the most difficult to grasp during the short-term test and future mass production. The incorrect chair mould temperature is enough to affect the size, brightness, shrinkage, flow pattern and material of the sample. And soon, if you do not use the mould temperature controller to hold the mass production in the future, it may be difficult.

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.

The mould company tells you that Table Mould(FURNITUREMOULD) processing has the following basic characteristics:

The machining accuracy is high. A pair of moulds generally consists of a die, a punch and a die, and some may be more split modules. Therefore, the combination, the lower die, the combined block and the cavity, require high machining accuracy to separate between the modules.

In small batches, mould production is not produced in batches, and in many cases it is often only produced one.

The shape is complicated, and some products such as automobile parts, aircraft parts, toys, household appliances, the surface shape is determined by various curved surfaces, and therefore, the cavity surface is very complicated. Some surfaces must be processed mathematically.

Process, table mould processing must use milling, boring, drilling, reaming and tapping. High hardness, excellent mould material, the main material of the mould is made of high quality alloy steel, especially the long life of the mould, often using Crl2, CrWMn and Leysite steel. This forged, machined and heat treated steel has stringent requirements.

Repeated operation, when using a table mould is to use a mould during its service life, it must be replaced with a new mould, so mould production is usually repeated.

Sectional drawings, sometimes without pattern mould production, no data, and processing materials according to profiles. This requires imitation precision and no distortion.
