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...
