Management of Injection Mold

By |2020-08-12T00:34:01+00:00August 12th, 2020|For all, plastic industry|

Mold management can be roughly divided into 3 different parts. That is mold development, mold use and mold maintenance. Therefore, for the effective mold management, companies or factories can start from the process to improve the problems of management. 1. The development of mold First of all, in terms of mold development, companies need to

Notes for Multi-material Injection Molding

By |2020-08-10T00:48:40+00:00August 10th, 2020|For all, plastic industry|

Over injection molding, like co-injection molding, bicolor injection molding and sandwich injection molding, belongs to multi-material injection molding technology. The basic idea of multi-material injection molding is to combine two or more materials with different characteristics to increase product value. The first injected material is called the base material or substrate. And the second type of injected material is called

How to Improve the Transparency of PP Products

By |2020-08-07T00:50:15+00:00August 7th, 2020|For all, plastic industry|

1. The matrix resin itself The transparency of the matrix resin itself has a great influence on that of PP products. To improve the transparency of PP, we can add a small amount of polyacrylate resin with good compatibility and excellent transparency. 2. Nucleating agent Significantly increase the crystallization velocity, the crystallization rate and crystal

Injection Molding Parameter | Rules for Speed Segmentation

By |2020-08-03T01:32:44+00:00August 3rd, 2020|For all, plastic industry|

The injection speed is a key parameter of injection molding for its close relationship with product quality. Determine the beginning, middle, and end of the injection speed segment. Moreover, realize a smooth transition from one set point to another. These can ensure a stable melt surface speed producing the desired molecule and the smallest

How to Increase the Gloss of the Injection Molding Products ? | Processes and Molds

By |2020-07-29T01:20:59+00:00July 29th, 2020|For all, plastic industry|

This article shows you the ways to improve the gloss of the injection molding products from two aspects. They are respectively injection mold and injection molding process. Injection mold 1. Make the mold cavity smooth If the mold cavity is poorly processed, with defects like scars, micropores, wear, roughness, etc., they can

Points That Need to Be Confirmed When Using Steel for Injection Molds

By |2020-07-31T02:33:55+00:00July 27th, 2020|For all, plastic industry|

There are 6 points that need to be checked when using steel in injection molds, considering the properties of steel. 1. Abrasion resistance When the blank is plastically deformed in the mold cavity, it moves and slides along the surface of the cavity, causing violent conflict between the surface of the cavity and

Bicolour Injection Molding | Manufacturing Process Characteristics and Mold Structures

By |2020-07-27T08:52:01+00:00July 27th, 2020|For all, plastic industry|

The Characteristics of Manufacturing Process 1. The bicolour injection molding machine is composed of two sets of plastic injection devices with identical structures and specifications. The nozzle should have a special structure according to the production method. Or it should be equipped with 2 molding dies with exactly the same structure that can

Ⅱ. Analysis and Elimination Methods for Unstable Sizes

By |2020-07-24T00:27:40+00:00July 24th, 2020|For all, plastic industry|

In this article, we will continue the analysis on the reasons for the unstable sizes of plastic parts. And the corresponding solutions will be put forward. We will think about the issue from 3 aspects. They respectively are: Mold failure The structural design and manufacturing accuracy of the mold directly affect the dimensional
