Plastic Injection Tooling

Dimensional instability of products in injection moulding

Instability of product dimension means that the dimension change of moulding parts exceeds tolerance limit. The reason may lie in injection moulding machine, injection moulds and injection moulding process.
 
(1) Injection Moulding Machine
 
The application of different types of injection moulding machines results in the difference of injection moulding conditions.
 
(2) Temperature fluctuation – check the faults of thermocouples or temperature controllers;
 
(3) Instability of screw speed – check hydraulic system;
 
(4) Unstable injection pressure – check whether there is a consistent buffer in […]

Aluminum Molds Or Steel Molds?

Conventional injection molding typically produces steel tools for millions of parts, however, manufacturing molds typically takes months and costs more. But what if production needs require less? This is the ideal place for aluminum molds.
Today, we will have an in-depth understanding of “aluminum molds” and “steel molds”.
Small batch production with aluminum mold
Mold production and parts in 15 days or less to complete mold manufacturing costs are low, from the current mold market: aluminum alloy market is relatively more stable than the […]

The impact of shrinkage on plastic processing

It is well known that in the plastic processing process, if various parameters are not well controlled, the plastic products are prone to shrinkage after being shaped, thereby affecting the precision of plastic processing. So, what are the adverse effects of shrinkage on plastic processing? Let’s take a look at it below:
1. Shrinkage after processing:
The shrinkage of plastics can be divided into two types: forming shrinkage and shrinkage after processing.
The shrinkage after processing is the shrinkage of the products […]

Precautions before plastic mould test

In JasonMould, after completing a new set of plastic moulds, test moulds are an indispensable part before mass injection moulding. The quality of the test results will directly affect the follow-up production of the factory. Therefore, in order to promote the large-scale production of plastic mould products, it is necessary to follow reasonable operation steps and record the technical parameters in the process of test.
 
Notices for plastic mould before test:
 
Whether the mould has been assembled or not. Secondly, attention should […]

What causes uneven color in injection molding

When we do injection molding, we often have defects in plastic products due to some inattention, which affects the efficiency of injection molding.
Below, we will simply analyze the problem of uneven color processing under the injection molding process.
In the process of injection molding, in order to make the plastic parts have more abundant colors, we will add appropriate amount of coloring materials to the raw materials. However, for one reason or another, color unevenness will occur.
So, what are the […]

Analysis of Pre-project of Plastic Mold

After fully understanding customer project requirements, it is necessary to fully understand and analyze the products. Confirm the feasibility of the project. So what do you need to know in detail? The main contents are as follows:
 
(1) Dimensional accuracy and correctness of related dimensions
 
Understand the specific requirements and functions of the product in the whole product. It includes dimension tolerance requirement, appearance requirement and assembly relationship of products.
 
(2) Reasonable demolding angle
 
The demolding angle is directly related to the demolding […]

Development Trend of Automotive Injection Molding Parts

Over the past 30 years, the application of plastics in automotive has been increasing. The consumption of automotive plastics in developed countries accounts for 8%~10% of the total consumption of plastics. From the material used in modern automobiles, plastic can be seen everywhere, whether it is exterior decoration, interior decoration, or functional and structural parts. The main components of the interior decoration are dashboard, door inner panel, auxiliary dashboard, sundry box cover, seat, rear guard panel, etc. The main […]

Application of ABS plastic on kitchen utensils

ABS raw materials have excellent comprehensive properties, good impact strength, good dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, molding processing and mechanical processing.
Kitchen utensils such as rice cookers, microwave ovens, ovens, food dryers, food shredders, food processing machines, juice presses, etc. often use ABS plastic materials.
1. The materials used in rice cookers should have excellent heat resistance, flame retardancy, water vapor resistance, and are non-toxic and odorless.
The main uses of ABS resin on rice cookers are handles, […]
