The important features associated with plastic molding

The important features associated with plastic molding

by | Oct 29, 2018 | General Injection Molding

Plastic molding, one of the most vital process required, is required to taken into utilize to shape plastic using a rigid frame or mould. Not to mention the way of using technique that allows for the creation of objects of all shapes and sizes with huge design flexibility for both simple and highly complex designs.

It starts with advanced techniques and placing liquid polymer into a hollow mould so that the polymer can take its shape – mainly with different ranges of pressure and heat required. You will get access to different plastic molding techniques that include rotational molding, injection molding, blow molding and compression molding to name just a few.

Plastic design

Plastic design process is not an easy part of the entire process. It is complicated and need assistance from top engineers and expert – who work in a planned way by focusing on various important things. Professionals who are working for plastic designs also remove uneven wall thickness by digging out material of triangle shape space and adding radius to compensate removed wall to reach even wall thickness.

Parts undercut are important that can’t be released from mold because of the undercut. You have to simply add a hole on top of undercut area. In order to make the plastic design process easier, they work on parts fitment. Original design is vertical tab that insert into plastic parts. Experts change tab into horizontal direction to ensure strong and unmovable fitment. They also provide you functional accuracy as injection molded parts can reach high accuracy

Injection molding machine

Use of injection molding machine is also important that depends on mold overall size, location ring, sprue bush, and ejection connector tap size with machine and a lot more. Waterline layout and nipple size, cavity layout, runner layout and weight, Mold steel type and hardness are some added features associated with it.

The most detailed mold test report is another important feature associated with plastic molding that assures easy and fast setting in mass production at client site.

Reaching the right and reputed plastic mold factory is important where you will get complete solutions for this process that is a popular manufacturing option – responsible for many car parts, containers, signs and other high volume items.

POM Material Injection Molding

POM Material Injection Molding

by | Oct 1, 2018 | General Injection Molding

Polyoxymethylene (POM) is a thermoplastic material also known as acetal. POM-H (polyoxymethylene homopolymer), POM-K (polyoxymethylene copolymer) is a high density, high crystallinity thermoplastic engineering plastic with good physical, mechanical and chemical properties, especially with excellent friction resistance.

POM is a crystalline plastic with a sharp melting point. Once the melting point is reached, the melt viscosity drops rapidly. Decomposition occurs when the
temperature exceeds a certain limit or the melt is heated for too long.

Copper is a POM degradation catalyst. Copper should be avoided where it is in contact with the POM melt.

 1. Plastic processing

POM has a small water absorption, generally 0.2%-0.5%. Under normal circumstances, POM can be processed without drying, but it must be dried for wet
materials. The drying temperature is above 80℃ and the time is more than 2 hours. The specific conditions should be based on the supplier’s data.

The proportion of recycled materials used is generally not more than 20-30%. However, depending on the type of product and the end use, it can sometimes be up to 100%.

2. The selection of plastic machine

In addition to the requirement that the screw has no stagnant area, the POM has no special requirements for the injection molding machine, and generally
can be injection molded.

3. Mold and gate design

The common mold temperature is controlled to 80-90℃, the runner diameter is 3-6 mm, the gate length is 0.5 mm. The gate size depends on the thickness
of the wall, and the circular gate diameter should be at least 0.5-0.6 times the thickness of the product. The width of the rectangular gate is usually 2 times
or more of the thickness, the depth is 0.6 times the wall thickness, and the draft angle is between 40′-1º30′.

Exhaust system

POM-H thickness 0.01-0.02mm width 3mm

POM-K thickness 0.04mm width 3mm

4. Melting temperature

POM-H can be set to 215℃ (190℃ – 230℃)

POM-K can be set to 205℃ (190℃ – 210℃)

5. Injection speed

Medium speed. If too slow, it produces ripples. If too fast, it is easy to produce grain and shear overheating.

6. Back pressure

The lower the better, generally no more than 200bar

7. Stay time in barrel

POM-H can be held at 215℃ for 35 minutes

POM-K can stay in 205℃ for 20 minutes without decomposition.

POM-K can be retained for 7 minutes at 240℃. If the machine is shut down, the barrel temperature should be lowered to 150℃. If you want to stop for a
long time, you must clean the machine and turn off the heater.

8. After machine stops

The cleaning barrel must use PE or PP. Turn off the heating and push the screw in the front position. The barrel and screw must be kept clean. Impurities or dirt can change the thermal stability of the POM (especially POM-H).

9. Post processing

For very warm parts and high quality requirements, heat treatment is required.

The annealing treatment effect can be carried out by immersing the product in a hydrochloric acid solution having a concentration of 30% for 30 minutes,
and then visually discriminating whether cracks have residual stress.

Analysis of uneven color of injection molded products

Analysis of uneven color of injection molded products

by | Oct 1, 2018 | General Injection Molding

The reasons and solutions for the uneven color of injection molded products:

1. The colorant is poorly diffused, and this often causes a pattern to appear near the gate.

2. The plastic or colorant has poor thermal stability. To stabilize the color tone of the part, it is necessary to strictly fix the production conditions, especially the material temperature, the amount of material and the production cycle.

3. For crystalline plastics, try to make the cooling speed of each part of the parts consistent. For parts with large difference in wall thickness, coloring agent can be used to mask the chromatic aberration. For the parts with uniform wall thickness, the temperature and mold temperature should be fixed. .

4. The shape and gate form of the part, the position has an influence on the filling condition of the plastic, so that some parts of the part have chromatic aberration and should be modified if necessary.

Analysis of the causes of color and gloss defects of injection molded products

Under normal circumstances, the gloss of the surface of an injection molded part is mainly determined by the type of plastic, the colorant and the finish of the mold surface. However, due to some other reasons, the surface color and gloss defects of the product and the dark color of the surface are often caused. The reasons for this and the solution are as follows:

1. The mold has poor finish, the surface of the cavity has rust, etc., and the mold is poorly exhausted.

2. The casting system of the mold is defective. The cold material well should be enlarged, the flow channel should be enlarged, the main flow channel should be polished, the runner and the gate should be polished.

3. The material temperature and the mold temperature are low, and the local heating method of the gate can be used if necessary.

4. The processing pressure is too low, the speed is too slow, the injection time is insufficient, and the back pressure is insufficient, resulting in poor compactness and darkening of the surface.

5. The plastic should be fully plasticized, but the degradation of the material should be prevented, the heat should be stable, and the cooling should be sufficient, especially thick-walled.

6. Prevent cold material from entering the part, and if necessary, use a self-locking spring or lower the nozzle temperature.

7. Excessive recycled materials are used, plastic or colorant is of poor quality, mixed with water vapor or other impurities, and the quality of the lubricant used is poor.

8. The clamping force should be sufficient.
