Six Points of Preparation for Mold Assembly

Familiarity with assembly procedure

 
The assembly procedure of injection mold is not only the process document of the assembly process and operation method of the mold, but also the technical document guiding the assembly work of the mold. It is also the basis for the assembly production plan and technical preparation. Therefore, before assembling, workers must read the assembly process regulations carefully, understand and master the whole process of assembling the mold.
 

A thorough understanding of assembly drawings

 
Assembly drawing is the […]

Harmful Effects of Improper Heat Treatment Process of Plastic mold

 
In the process of plastic mold processing, cracks or deformation, easy oxidation and decarbonization of the surface are mainly due to the failure of the mold. The main reason for the failure of plastic mold is the improper heat treatment process, such as the improper selection of heat treatment process parameters such as heating temperature, holding time, cooling speed and so on.

First of all, it is about the influence of oxidation and decarbonization, mainly because die quenching is stopped […]

5 Factors Reflecting Technical Level of Mold Factory

The level of mold technology ultimately manifests itself in many aspects, such as mold manufacturing cycle, mold service life, mold accuracy and stiffness, mold manufacturing cost, mold standardization and so on. These are also the basis for evaluating the economic and technical indicators of molds.

Mold manufacturing cycle

 
 
The mold manufacturing cycle reflects the production technology level and organization management level of the mold enterprises. When making the mold, we should try to shorten the manufacturing cycle of the mold. At present, in order to shorten the […]

Common Defects in Plastic Injection Mold

As we all know, some defects often occur in injection molds after forming, which seriously affects the normal use of the workpiece, and even leads to the unusable workpiece, which will seriously affect the cost and efficiency of the manufacturing workpiece. Therefore, we must do a good job of preparation before moulding, and find out the specific causes of these defects.

Lack of glue.

 
(1) If one of the multi-mode cavities lacks glue, it may be due to the different size […]

How to Improve Quality of Injection Mould Effectively?

In order to produce qualified plastic injection moulds, we must provide the quality of plastic injection moulds. What measures can we take to improve the quality of plastic injection moulds?

A complete set of plastic mould production management system is established to realize the computer information management system of product data management, process data management, plan management and schedule management in the process of mould production management, including the formulation of mould production plan, mould design, process formulation, workshop task […]

How to Identify The Quality of Injection Parts

From three points, we can see the quality of injection parts.

First, look at the appearance
 

Seewhetherthe injection parts are complete and whether they are deformed or not;

 

Whether the injection parts are uniform in color, whether there is obvious color difference, and whether the color is bright and translucent.

 
Second, touch the product
 

Touch the the surface of the injection part to see whether smooth, and whether there are burrs around the handle;

 

Whether theinjection parts have been naturally aged, the aging is reflected in […]

Six Systems of Plastic Mould

The functional structure of plastic mould system is mainly composed of six systems: pouring system, temperature regulating system, forming parts system, exhaust system, guiding system and ejection system. The pouring system and forming parts are the parts directly contacted with plastics, and change with plastics and products. They are the most complex and most changeable parts in plastic mould. It is required to process the parts with the highest smoothness and accuracy.
 

Gating system:

The pouring system refers to the runner […]

Four Key Points Affecting the Quality of Injection Mold

1) plastic materials
 
The complexity of plastic material properties determines the complexity of injection moulding process. The performance of plastic materials varies greatly with varieties, brands, manufacturers and even batches. Different performance parameters may lead to completely different forming results.
 
2) injection temperature
 
The melt flows into the cooling cavity and loses heat due to heat conduction. At the same time, the heat generated by shearing may be more or less than the heat dissipated by heat conduction, mainly depending on the […]

Difference Between Soft Mold and Hard Mold

Soft mold refers to the mold made of steel such as NAK80, which can be machined directly without heat treatment, and can be put into use directly after processing. This material is generally pre-hardened when used. Hard mold refers to the mold core material is annealed before mechanical processing, and then heat treatment after mechanical processing, generally hot. After treatment, electrical processing and remanufacturing are also needed.
The service life of hard mold is much longer than that of soft mold.
Soft mold is a simple mold made […]

Structural Factors to be Considered in Plastic Injection Mold Design

 

Parting surface, that is, the contact surface between the die and the punch when the die is closed. The selection of its position and form is influenced by the shape and appearance of the product, wall thickness, forming method, post-processing technology, die type and structure, demoulding method and the structure of the forming machine.

 
2, structural parts, namely, complex mold slide, oblique top, straight top block. The design of structural parts is very critical, which relates to the life of […]
