With the rapid development of society, large- and small-scale enterprises are also living with the survival of the fittest, and how to make diversified and sustainable development of the enterprise more important. The application of rapid  die casting  change in the press greatly enhances the competitiveness of the company, and makes the  aluminum alloy die casting supplier  company's products tend to be small-volume and diversified. First, parallel operations Parallel operation means that two or more people are engaged in switching operations, and parallel operations are most likely to have the effect of shortening the internal operation time. When working in parallel operations, the coordinated actions between people must be skillfully exercised, with particular attention to safety. Do not cause accidental injury due to negligence.

First, open up the assembly site. When assembling a  plastic injection molded medical box , a good assembly site is needed. The site must be clean and tidy and free of debris. At the same time, the necessary tools, clamps, gauges, and other necessary assembly equipment used in the assembly must be prepared and wiped. Clean, open up a venue for civilized production. Second, prepare standard parts and related materials. Each set of  injection mold  has a lot of standard parts, such as screws, pins, nuts, springs, etc., although their number is not many, but many specifications, in order to smooth the assembly, these parts must be found one by one at the beginning of the assembly, It is easy to find when preparing for assembly. In addition, auxiliary materials required for assembly, such as rubber and adhesives, are also prepared as required.

Check the check parts According to the parts list on the assembly drawing, check whether the number of  injection molded products  is enough, then carefully clean each part, and then carefully check the main parts, such as the cavity shape and size tolerances to identify the gap between the various parts of the surface, processing quantity, with or without deformation and crack defects. Master  injection molding  acceptance technical conditions The mold acceptance of technical conditions is the mold quality standards and acceptance basis, but also the assembly process basis. The acceptance technical conditions are mainly the technical requirements of technical agreements and product drawings signed with customers and the quality standards issued by reference countries. Therefore, before assembly, the workers must fully understand these technical conditions so that they can pay full attention to the assembly qualified mold.

First, be familiar with the assembly process The assembly process specification of the  plastic injection mold  is the process document of the mold assembly process and operation method, and also the technical document for guiding the mold assembly work, and is the basis for the assembly production planning and technical preparation. Therefore, workers must carefully read the assembly procedure before assembly to understand and master the entire process of assembling the mold. Second, thoroughly understand the assembly drawing Assembly drawing is the main basis for mold assembly.  Plastic injection auto parts  is an example. In general, the structure of the mold largely determines the assembly sequence and method of the mold. In-depth analysis of the assembly drawing, assembly drawing and parts drawing, can understand the structure characteristics and work performance of the mold; understanding the role of various parts in the mold and their mutual relations, ...

There may be one or more reasons for the formation of shrink marks, including the method of mold processing, part geometry, material selection, and mold design. The choice of geometry and material is usually determined by the raw material supplier and is not easily changed. However, there are many other factors related to mold design that may affect shrinkage on the part of the  molding manufacturer . Cooling runner design, gate type, and gate size may produce multiple effects.  5-Axis precision CNC milling service is a difficult geometry. For example, small gates, such as pipe gates, cool much faster than tapered gates. Premature cooling at the gate reduces the filling time in the cavity and increases the chance of shrinkage marks. For molding workers, adjusting the processing conditions is one way to solve the shrinkage problem. Fill pressure and time significantly affect shrinkage. After the part is filled, excess material continues to fill the cavity to compensate for...

CNC milling  or manual milling is a machining process for machining prismatic parts. A milling cutter with a rotating cylindrical cutter head and a number of flutes often is referred to as end mills or end mills, which can move along different axes for machining slots, grooves, outer contours, etc.  Machine tools for milling are called milling machines, and  CNC milling machines  are usually index-controlled machining centers.  Precision machined end bell  is a CNC milling machine. Milling includes manual milling and CNC milling. Milling takes place in the machining shop.

In the CNC machining process, the conditions that is easy to break the knife: This is the result of the operator's experience. Beginners may not consider these aspects. Therefore, similar encounters in processing may require attention. (1) Generally, it is very easy to break the knife if we do not pay attention when we mill the trough. If we do not promptly knock out the place that has not been milled in the middle, the cutter will snap off during the fast milling. (2) We did not pay attention to the processing contents on the drawings during processing, and we also had broken knife or plane collision when our code molds had just processed places. (3) The knife was not caused by machining the knife. When finishing, we must remember to test the pendulum. We must also be familiar with the material of each template when processing. We must be familiar with the hardness of these materials to process, and different materials must be treated differently. The CNC milling aerospa...

The pillar hole is one of the main precisions of the  CNC machining  model. Guide post hole: guide post hole is more accurate, we have to be careful when doing it. When doing the guide post hole, we may also use  CNC milling  cutters to mill a bottom hole first. At this time, we have to use the caliper to measure the hole size. We can't see the phenomenon that the hole is large when the hole has not been started yet. No problem, then we will be on the sickle. Note: It is also necessary to pay attention to the use of a trowel. The trowel must be set twice to align the workpiece surface with the side wall of the hole to be bored.  When the hole is drilled, we have to test the knife. The general test knife is five millimeters. After trying the knife, we use the internal diameter to measure. We must compare the actual size of the hole with the size of the hole we want to make, and then adjust the scale of the boring knife until it reaches the size of the bori...

The pin hole is one of the main precisions of the  CNC machining  model. The processing method for making a pin hole is that: using a ten-mm pin hole as an example, we will use a 9.0 drill bit to make a hole first, then use a 9.8 bit to make a hole, and then use a ten-mm reamer to ream the hole. But here we should pay attention to when we drill 9.8 bit when we should use a 10-mm pin to try on the pin hole, we can not be sure 9.8 drill hole drilled out must be 9.8, there will be some error, if When we try to insert a ten-mm pin and we can't put it in, we will continue the drilling procedure later.  When using a reamer after drilling, we must also pay attention to, when the reamer twists the first hole, we have to use 10 mm pin to test the hole, when you find that the 10 mm pin can be just tight, continue the next program.

Computer Numerical Control machines ( CNC machining ) are automated milling machines that can produce industrial components without human assistance. They use coded instructions sent to internal computers to enable factories to make parts quickly and accurately.  There are many different types of CNC machine tools, ranging from drill bits to plasma cutters, so they can be used to make a wide variety of parts.  CNC milling ,  CNC turning  and  micro CNC machining  are the common things. Although most of the industry is used in manufacturing, the hobby version of most machines can be used in private homes.

In general, die  casting machine  replacement mold is divided into two kinds of internal and external mold change, then how to improve the internal  die casting  machine efficiency?     1) Simplify mold taking action     Reduce the need to rotate during the removal and installation of the mold, and can also simplify the multiple pick and place actions as one action, and place the single action at one time; use the mounting frame, template, standard tools, the same size of the same type of screws and bolts wait.     2) Multiple people work in parallel    In order to shorten the time for changing the mold during shutdown, many people can change molds at the same time during the time of mold change. This should pay attention to the clear division of labor and mutual supervision so as to avoid extraneous actions, but also to avoid operating omissions.     3) shorten the adjustment time  The first analysi...

At present, the proportion of  plastic injection molded product  in the entire mold industry is about 30%, and the proportion in the import and export of molds is as high as 50 to 70%. In recent years,  China plastic injection molding  have developed rapidly. The application of plastic products has become increasingly widespread, providing a very broad market for plastic molds. In addition, under the impetus of high-tech driven and pillar industry application needs, China's plastic molds have formed a huge industrial chain, from upstream raw and auxiliary materials industry and processing and testing equipment to downstream machinery, automobiles, motorcycles, and household appliances. Several major application industries such as electronic communications, construction and building materials, etc., which shows that plastic mold development is alive.

Materials for precision machining such as  CNC machining , fall into two categories, metallic materials, and non-metallic materials. For metals, stainless steel is the largest in hardness, followed by cast iron, next followed by copper, and finally aluminum.  Precision machined brass part  is one of the choice of the CNC milling. The processing of ceramics and plastics are the processing of non-metallic materials. Stainless steel material for precision machining The first is the requirement for the material hardness. For some applications, the higher the hardness of the material, the better. It is only limited to the hardness requirements of the machining parts. The processed material cannot be too hard. If it is harder than the parts, it cannot be processed. Secondly, the material is moderately soft and hard, at least one grade lower than the hardness of the parts. At the same time, it depends on the function of the device being processed and the proper select...

The rapid change system for  plastic injection molding  has been used extensively in many fields. And in the previous article, we have know some strong points, so let us explore advantages of  plastic injection molding in China  continually. 1) The use of quick die change system can greatly increase the efficiency of die change and reduce die change time. Generally, the die change and die clamping operation of the injection molding machine only takes three minutes, and the oversize die changeover only takes about ten minutes. 2) The dedicated disk thickness is about 5-6cm, and the occupied space is small, which does not affect the open space of the injection molding machine; 3) It is easy to operate. Any non-professionals can use only about 1 minute of training to be proficient.
