Injection syringe mould

Generally, high-quality silicone should be selected, which meets the following characteristics (here, Hongye silicone is used as an example): 　　①The mold silicone rubber has good operating performance.　　 How to make silicone molds durable?　　 One is the choice of silicone raw materials.What is a silicone mold?　　

Silicone mold is a special mold glue for making handicrafts. The characteristics of silica gel are high temperature resistance, corrosion resistance, strong tear resistance, and high simulation accuracy. Before repairing the mold, according to the actual situation of the bad phenomenon of the silicone mold, a detailed analysis and research should be carried out, and the remedy method should be proposed after finding the cause of the mold defect. Therefore, it is necessary to repair the malfunctioning silicone molds. However, in the process of using silicone molds, failure forms such as collapse, deformation, wear, and even breakage often occur.　　

This simulation can test geometrical constraints and critical regions of overlapping motion between molds, parts, and material transfer devices.The complex mold used on the multi-station press must match the performance of the press, so a device called a trial press is needed to debug the mold and shorten the installation time..　　 During the stretching process, the blanking die that presses the sheet between the stretching ring and the blanking part is critical to the quality of the part forming. The optimal blank holder force depends on the geometry of the deep drawn part and its material properties.

Computer simulation of the forming process is extremely important. If the blank holder force of the polystyrene formwork Injection syringe mould is too small, wrinkles will be formed in the stretched part; if the blank holder force is too large, when the sheet material is low carbon steel, the material cannot be fully stretched and will be torn. In order to reduce the number of mold changes at least, most companies will process the parts on the multi-station press according to today's fully automatic Large-scale multi-station presses for plate parts require corresponding blanking and die technology to achieve good deep drawing functions. Under normal circumstances, it is economical to change the mold when the production batch of the same part is between 30,000 and 5,000.　　 The development of tool and mold technology is due to the application of computers, the adoption of new or improved materials, the improvement of lubricants and the integration of computer manufacturing

Large three-way valve

In aluminum processing, the Large three-way valve wastewater treatment system includes an automatic acid addition system, an automatic alkali addition system, an automatic pH detection system, and an automatic discharge system for qualified wastewater. It should also be explained here that the sodium hydroxide used between the molds is solid caustic soda, which has a high cost.

Since there is no operation process to follow, the addition of caustic soda and the discharge of the bath are arbitrary, and sometimes it is caused by the bath. The phenomenon that the concentration is oversaturated and part of the caustic soda is not dissolved. This not only caused waste, but also increased environmental pollution.　　

After the completion of the new mold room, the alkali used for cleaning the mold was changed from flake caustic soda to the liquid caustic used in the oxidation production line, which not only reduced the cost, but also was convenient to operate, with accurate dosage and no waste.　　 The mold room is built outside the oxidation workshop near the water treatment area. There are two mold washing tanks in it, and the tank liquid is sodium hydroxide solution.

When the aluminum ions in the bath exceed the standard, they are discharged to the waste alkali storage tank in the basement or neutralized by air agitation. In the original design of extrusion production, there is no design process and operating procedures for mold cleaning. It is based on experience. Because there is no requirement for process parameters, a large amount of alkali waste and environmental pollution are caused.　　Building the profile mold room near the oxidation production line, and comprehensively treat the waste water and oxidation waste water produced by it, which saves money and is conducive to environmental protection. It is an effective treatment method.

Medical Treatment Drip Chamber Mould Factory

The temperature of the heat sink was significantly lowered, so the ideal heat sink shape was not obtained. The problem of stuck bolts due to thermal deformation hinders practical use. In addition, the complicated forging shape increases the deformation resistance during forging, which becomes a major difficulty in forming. Research and development of the world's first forged steel brake discs with fins have been used in recent high-speed Shinkansen vehicles.

In manufacturing, there is a reverse included angle between the brake sliding surface and the thermal deformation. Use pre-deformation to reduce thermal deformation. When the wheel is installed, the sliding surface and the corresponding sliding material plane become parallel.The practicality of forged steel brake discs with heat sinks..

Therefore, the process plan for the forged steel brake disc with the heat sink is also determined. In the past, the shape of the heat sink was forged three times, and the deformation resistance of the material was increased. The original shape of forged steel brake discs with heat sinks is a split type that can be replaced by (a) stress expansion coefficient (b) fracture toughness value according to the vehicle marshalling state.

In addition, in order to Medical Treatment Drip Chamber Mould Factory reduce thermal deformation, a certain amount of pre-deformation is given in the opposite direction from thermal deformation during manufacturing. Therefore, in order to improve the processability of heat sink forming, research has been conducted on the adjustment of die cooling time, the increase of die temperature, the development of high-temperature adhesion lubricants, and the development of molds to prevent defects in heat sinks.

Due to the excellent heat-resistant crack resistance of forged steel, it is not necessary to replace the disk, so the original split type is improved to the integral type, and the deviation of the installation bolt hole distance is also prevented.

Plastic Infusion Apparatus Parts Manufacturers

They will not change in the subsequent heat treatment process. Inspection and use results After the heat treatment of the high chromium roll, the high chromium cast iron on the roll surface and the gray cast iron of the roll core were inspected. The high chromium rolls developed by our factory have reached the current level of similar foreign rolls, and some quality indicators have reached the current international level, setting a precedent for the successful use of high chromium rolls on old hot strip mills.. The higher the tempering temperature, the greater the effect of reducing the retained austenite and residual stress, but the excessively high tempering temperature will significantly reduce the hardness, which is obviously not what we want.

The choice of fire temperature The tempering temperature of high chromium cast iron can be seen from the table according to different situations. The sample can get the desired structure under the air-cooling condition, but the half-cooling time is the hardness of the required roll surface, which is equivalent to one. The half-cooling time is a significant increase in the hardness of the sample. The morphology and distribution of the eutectic carbides of the high chromium roller and the matrix structure of the eutectic carbides are mainly determined by the solidification rate of the alloy composition and the gravity coefficient for centrifugal casting.　　According to past experience,

due to the residual stress of the composite roll, its hardness is higher than the hardness of the sample cut from the roll body, so it can be determined that the matrix and hardness value obtained at this cooling rate meet the requirements.The choice of cooling rate In order to verify whether the selected high chromium cast iron can Plastic Infusion Apparatus Parts Manufacturers obtain the required matrix structure and hardness under air cooling conditions, the samples are cooled to the inside for controlled cooling according to the half-cooling time, and part of the samples are tempered ,

The results are listed in the table and vary widely. During centrifugal casting, the eutectic carbides formed in high chromium cast iron are very uniform due to the large cooling rate and coefficient of gravity, which are in the pattern of typical eutectic carbides of high chromium cast iron. The hardness of the samples tempered at medium temperature is higher, so this tempering temperature is selected. The test results are compared with the data of high grid rolls from some foreign manufacturers
