How to solve the problem of IML injection molding

Reason: This IML robot product, after the sheet is screen printed, is put into the mold for injection molding. Since the unfolded area of the sheet is inconsistent with the area of the front film core, the whitening phenomenon is caused by poor edging.

Analysis: The projected area of the sheet is inconsistent with the projected area of the mold;

1. Injection molding machine features

Grade: Haitian 50T

  Clamping force: 50t Plasticizing ability: 42g

2. Mold features

In-mold number: 1x2 Inlet method: point gate Top-out mode: ejector pin-out Mold temperature: 70°C (constant temperature machine)

3. Product signs

Material: PMMA IRK 304 Color: Transparent Product weight (single piece): 2.4g Water mouth weight: 8.2g

4. Analysis of adverse causes

a. The projected area of the sheet is inconsistent with the projected area of the mold.

b. Deviation when hot pressing the slice material.

c. When placing the sheet, the method is not standard deviation.

5. Countermeasures

a. Increase the projected area of the sheet.

b. Adjust the hot press die cutting die.

c. Add positioning fixtures for stereotypes.

What is the process selection of iml


1. According to the product requirements, the material, thickness and type of ink (UV or solvent) of the appropriate sheet.
2. Select the appropriate series of special IMD inks according to the material of the sheet, such as: Solvent-based selection of Baolong brand.
a, ordinary PC sheet Select Noriphan HTR series
b. Thin PC sheet Select Noriphan N2K series
c, PET sheet Select Noripet series
d, PMMA sheet selection Noricryl series
3. According to the type of ink, such as solvent type or UV, choose the appropriate drying method and drying equipment.

How to change the high-speed injection molding machine from semi-automatic to automatic

1. Press the automatic mode first, then press the clamping mode.
2, the classification of High Speed Injection Machine:
(1) Classification according to the plasticization and injection methods of raw materials.

(2) According to the shape and structure of the injection machine.
(3) Classified according to the processing capability of the injection molding machine.
(4) Classified according to the special use of the injection machine.
3. In the cost of plastic products, the cost is mainly composed of two parts:
1. Raw material costs, to obtain greater profits, save raw materials, reduce the scrap rate of products is the most direct and effective method;
Second, the production cost, want to save production costs, power saving and in the production of the same product time, shorten the injection cycle is an effective method.
In short, in order to obtain greater profits, it is necessary to save raw materials (reducing the wall thickness of plastic products - thin-walled products) and improve the yield rate. It is the easiest and quickest method, and secondly, energy saving (power saving) and high efficiency (short injection molding) The molding cycle) is a good way to increase profits, which is also the purpose of developing high-speed injection molding machines.

What are the types of labeling machines

The flat  Labeling Machine Manufacturers realizes the labeling and filming on the upper plane and the upper arc surface of the workpiece, such as a box, a book, a plastic shell, etc. There are two methods of rolling and sucking, which are mainly selected according to efficiency, precision and bubble requirements. .
The round bottle labeling machine realizes labeling or filming on the circumferential surface of cylindrical and conical products, such as glass bottles and plastic bottles, which can realize functions such as circumferential, semi-circumferential, circumferential double-sided, circumferential positioning and labeling, etc. Vertical labeling and horizontal labeling.
The side-type labeling machine realizes labeling or filming on the side plane and side arc surface of the workpiece, such as cosmetic flat bottle, square box, etc., and can be equipped with round bottle labeling equipment, and at the same time realize round bottle labeling.
According to different adhesive coating methods, it can be divided into self-adhesive labeling machine, paste labeling machine (upper paste labeling machine, glue labeling machine) and hot melt adhesive labeling machine.
According to the degree of automation, it can be divided into automatic, automatic, semi-automatic and manual labeling machines.
According to the realization of different labeling functions, it can be divided into plane labeling machine, side labeling machine and circumferential labeling machine.
Labeling machine mainly includes: self-adhesive labeling machine, sleeve labeling machine, round bottle labeling machine, beer labeling machine, semi-automatic labeling machine, labeling machine, automatic labeling machine, automatic labeling machine, labeling machine , automatic paste labeling machine, hot melt adhesive labeling machine. These products can be flat-paneled, single-sided or multi-faceted packaging, cylindrical paste, partial or full-covering cylinder paste, dents and corners.

The development trend of food packaging containers

The main development trends of glass containers: first, thin wall, lightweight and strengthening; second, the development of the use of advanced bottle mouth sealing technology, research on new caps inside and outside coatings and sealing materials; the third is to study microwave heating glass bottle food technology. Due to the hygienic and aesthetic characteristics of glass containers, glass containers have attracted great interest from consumers in the current stricter food hygiene regulations, and have broad development prospects.
1 Good mechanical properties. The metal container has a large strength relative to other packaging containers, such as plastic, glass, paper containers, etc., and has good rigidity and is not easily broken. Not only can be used for small sales packaging, but also the main container for large transport packaging.
2 excellent barrier properties. The metal sheet has excellent barrier properties compared with any other materials, and has good gas barrier properties, moisture resistance, light blocking properties, and aroma retention properties, and the sealing is reliable, and the product can be reliably protected.
3 easy to achieve automated production. The production of metal containers has a long history, and the process is mature with a complete set of production equipment, which has high production efficiency and can meet the packaging needs of various products.
4 beautifully decorated. The metal material has good printing performance; the pattern logo is bright and beautiful, and the obtained packaging container is attracting attention, which is an excellent sales package.
5 various shapes. The metal container can be made into various shapes according to different needs, such as a circular shape, an elliptical shape, a square shape, a horseshoe shape, a trapezoidal shape, etc., which not only satisfies the packaging requirements of different products, but also makes the packaging container more change and promotes sales.
