Generally affect the injection machine of the important factors including choice mould，products, plastic, molding requirements, etc. Therefore, before molding we must collect or meet the following information.

1. Mold size (width, height and thickness), weight, special design, etc.

2. Plastic types and quantities (single materials or variety of plastic)

3. The appearance of the injection product size (the length, width and height and thickness)

4. Molding requirements, such as quality condition, production speed and so on.

lShould choose the products and plastic suit machine

lChoose suit for mould machine, ensure mould can put under the machine.

lThe mould and finished product determine demold is enough to make products out.

lThe products and plastic decided to “the clamping force” tonnage

lAlso confirm injection speed

The ascension of the machine performance and the transformation of course can improve the production efficiency, but also often increase investment costs and operating costs, therefore, before the investment evaluation should considerate, then can choose the best type injection machine.

Problem one: The product size not accuracy:

Reason 1: The material liquidity is strong, have difference with shrinkage rate.

Reason 2: injection machine and injection molding conditions

1. Shoot rubber pressure is too low

2. The pressure is too low

3. Mould temperature is not appropriate

4. Cooling time is too short

5. The clamping force not enough

Reason 3：product and mold design

1. The product size tolerance is too strict

2. Mold hard not enough

3. Enter the water forms and position not suitable

Flash:

1.the clamping force is not enough

2.plastic measurement too much

3.feed tube temperature is too high

4.shoot is high and holding pressure is too big

Solution:

1.Make sure the lamping force is enough

2.Make sure measuring position is correct.

3.Reduce resin temperature and mold temperature.

4.Check injection pressure is proper.

5.Adjustment injection speed.

6.Change holding pressure or change position.

Welding mark:

Product welding mark usually due in low temperature and caused by small pressure.

1.The temperature problems

2.The nozzle temperature is too low

3.Mold temperature is too low

4.Plastic melt temperature not all

5.Injection speed too slow

6.Injection pressure is too slow

The mold problem:

1.Gate is too small

2.Shunt way too small

3.Nozzle is small

4.Core migration, cause on side thin.

5.Parts exhaust bad

PVC injection molding machine is special type of injection molding machine from China Dakumar, is specialized in making the plastic products like PVC pipe fittings. Dakumar offer this high function PVC injection molding  machinery and provide PVC injection molding machine sales service like installation,debugging and maintainance.
PVC injection molding machine is on the base of general injection molding  machine, equiping with special components to meet the special requirements of the PVC material.
1.Special plasticizing components of the PVC injection molding machine.
Within the injection of PVC, the temperature reached to 200℃,PVC will release the Corrosive gas when the PVC touched the steel mayerial. So, we should plate chrome on the screw and nozzle (with enlarged nozzle hole).
2.Special barrel of PVC injection molding machine
Forced cooling by compressed air through air channels in individual zones with independent control, or screw oil cooling connect to oil temperature controller to avoid thermal degradation of PVC powder in barral.
3. Special cooling system of PVC injection molding machine
The PVC injection molding machine has two cooling system: oil cooling system and water cooling system. The two cooling system is screw and barrel for the large size PVC injection molding machine.
4. Special motors for PVC injection molding machine
Enlarged hydraulic motor: a. to achieve the goal of high efficient  plasticizing ability. b. to meet the requirement of ultra-high screw torsion of PVC specialized screw.
If you are looking for PVC injection modling machine or PVC injection mould ,pls contact us. We will offer you the suitable PVC injection molding machine and we can guaruantee one year amendment with our after-sales like  installation, debugging and maintainance.

Plastic products with mixed color are popular in Africa especially,for example, mixed color basin,mixed color container… but if you want to set up the mixed color products production line,you need to custom multi-color plastic moulds making,mixed color molding machine and auxiliary equipment.

First, the multi-color plastic moulds making is same as normal single color moulds, it means you can use the same mould to get the part with single color or mixed color.But the moulds should be cold runner, because it would be better for the color change. And the key point is the mixed color molding machines, this kind of machine is with 2 pieces of screws and barrels, different color of plastic material will come from each barrel, and then the material come into the same nozzle.the design of nozzle for the injection machine is crucial,and the design depends on the color pattern which you want to make. If you need the mixed color products production line, please contact me.
