What is Plastic Cap Mould?

Plastic Cap Mould is an abbreviation of molds includes compress molding, extrusion molding, injection molding, blow molding and low foam molding. It is a tool to make a fixed shape products with kinds of plastics. The tool is mostly have two parts called male mold and female mold. There is some empty space after the male mold and female mold closed. That is the plastic product`s shape. We put some melt plastic to fill the empty space and then we got a plastic part after it was cured.

Benefits of Plastic Cap Mould

 

 

Multi-cavity point
Plastic bottle cap molds have mature technology from 4 to 32 cavities, simplified hot runner work, and low cost.

 

High efficiency
The plastic bottle cap mold adopts a simplified dispensing hot runner, no glue mouth waste, and the cycle reaches 5 seconds.

 

High life expectancy
The cavity of the plastic bottle cap mold is made of high-quality mold steel, and the guide post and guide sleeve of the mold are lubricated without oil, which has the strong advantages of no pollution and a service life of up to ten million times.

 

The blade is specially designed
The unscrewing ring knife edge of the plastic bottle cap mold adopts a split structure, which can make the blade not deformed, the positioning is accurate, the replacement is easy, and the mold is closed without pressure. defect.

Continuous Compression Moulding

Process of Plastic Cap Mould

 

 

Clamp the mold based on the tonnage requirement
After completing the mold for the plastic bottle cap design, you will need to clamp the mold according to the tonnage requirement of your machine, which will allow you to connect the feeding system with the mold. Be sure to follow the tonnage requirement to ensure that your mold will hold its place during the production period.

Feeding the plastic materials into the mold
Next, it's time for you to feed the plastic materials into the mold. You will need to do this before starting the injection molding operation to ensure that the plastic materials will be ready when you start the production operation.

Using the extrusion mechanism
For plastic bottle cap production, you will need to use the extrusion mechanism, as this is the mechanism that works best to produce tube-shaped products. With the extrusion mechanism, you can create plastic bottle caps that will have the best design, along with the threading system inside the cap.

The cooling process of the injection-molded plastics
Now, the extrusion process will be complete, and the injection-molded bottle caps will need to cool down before you can eject them from the mold. Depending on various factors, you will need to wait for different cool-down times for the plastic bottle caps.

Ejection of the bottle caps from the mold
Now, it's time to remove the injection-molded caps from the mold cavities. The mold will be able to handle thousands of production cycles, so you can repeat the process again as needed.

 
How to Maintain Plastic Cap Mould?
 
01/

Guarantee product quality
To ensure that the plastic mold can produce qualified plastic parts stably and reliably, the plastic bottle cap mold must be in good working condition. When the injection mold is working, it is always impossible to stay in working condition. There will always be one or another situation, such as the lack of oil in the guide post and guide sleeve, which will cause action blockage, and the loosening of the fasteners, which will cause deformation of the action. These small problems will adversely affect the quality of the product. Overcome these minor problems and make the mold in good working condition.

02/

Reduce downtime
During the use of plastic bottle cap molds, there is always the possibility of major failures that require shutdown and maintenance, and can no longer continue working during shutdown. Therefore, it is hoped that the shorter the shutdown time, the better, and the fewer the shutdown times, the better. The major failure of the mold is often not sudden. It has an accumulation process.

03/

Timely maintenance
For example, the lack of oil in the sliding part will lead to increased wear. If it can be maintained in time and oiled in time, it will reduce wear. Delaying the shutdown of the mold, as in the lateral core pulling mechanism of the inclined guide column, the screw fixing the inclined guide column is loosened, which causes the position of the inclined guide column to change. In severe cases, the inclined guide column can be deformed or even broken. These problems will be discovered in time during maintenance and tightened in time, and these similar problems will not occur.

04/

Reduce operating costs
In the process of using the mold, there are many operating costs, such as inspection costs, adjustment costs, lubricant costs, repair costs, etc. The sum of these costs is the operating cost. Of these costs, the largest amount is repair costs. If the maintenance of the mold is not good, many extra repair costs are often paid, which makes the mold unable to work normally and increases the operating cost.

FAQ
 

Q: How long does a plastic mold last?

A: Plastic injection molds last from hundreds to over a million cycles. A plastic injection mold lifespan depends on its environment, maintenance, structure, SPI classification, and other factors.

Q: Are plastic Moulds reusable?

A: Once it has been molded and sets, the plastic is very durable and long lasting. However, if there are any sculpting issues or a change of heart, the plastic can be melted again to make a change or completely reuse the plastic toward a new project.

Q: What are the types of mould maintenance?

A: You need to carry out preventive maintenance daily, monthly, or weekly. It ensures the smooth operation of molds. It comprises mold cleaning, inspection, and lubrication of parts for daily maintenance. The ejector units need a thorough cleaning for routine maintenance.

Q: How long does an injection mould last?

A: Class 103 – These molds are built for a maximum lifespan of 500,000 cycles – medium production volume. The mold base must be a minimum hardness of 8 Rc, and the cavity and cored must have a minimum hardness of 28 Rc. Class 104 – These molds are built to not exceed 100,000 cycles – low production mold.

Q: What is mould in plastic?

A: A mold is a hollow metal block into which molten plastic is injected to from a certain fixed shape.

Q: What is plastic mould technology?

A: Plastic moulding is the process of pouring liquid plastic into a certain container or mould so that it hardens in that customized shape. These plastic moulds can then be used for a wide range of purposed. There are 5 types of plastic moulding that is considered to be the most effective and most popular.

Q: What is plastic mould made of?

A: The plastic mold is made from a combination of steel plates and other mold components, coupled to form an overall mold, which is then reliably assembled and installed in an injection molding machine, then applies a thermoplastic resin to the desired shape to fulfill the intended purpose.

Q: What is the difference between plastic casting and molding?

A: The main difference between molding and casting is the use of the material in the process. Casting will typically involve metal, while molding focuses on plastics. In both cases, the melted material goes into a die or mold to create the final form.

Q: What is the function of plastic cap?

A: The bottle cap has the function of keeping the contents of the product airtight, and also has the functions of anti-theft opening and safety, so it is widely used in daily chemical, food, beverage, wine, chemical, and pharmaceutical bottled products!

Q: What is the meaning of plastic cap?

A: The process involves the injection of melted plastic into a mold, which is made of steel. The mold itself has cavities that will form the parts; once injected, the molten plastic fills the cavities and the rest of the mold.

Q: What is the process of plastic mold?

Q: What is the process of making plastic caps?

A: Most plastic bottle caps are manufactured through a process known as injection moulding. In this process, thermoplastic polymer pellets are heated in a metal hopper to the point that they become very soft and flexible. (It would be at this stage that any custom colouring would already be added).

Q: What is the process of mould casting?

A: Permanent mould casting. Permanent mould casting is a process for producing a large number of castings using a single reusable mould. The casting process simply involves pouring molten metal into a mould where it cools and solidifies. The mould is then opened, the casting removed, and the mould is reused.

Q: Which moulding is used for bottle caps?

A: injection molding Most plastic bottle caps are manufactured through a process known as injection molding. This process enables each finished one to achieve high precision, uniformity in size, shape, and high surface finishing.

Q: How do you clean plastic Moulds?

A: There are five primary cleaning methods to consider: Chemical cleaning,Ultrasonic immersion cleaning,Dry ice blasting,Soft plastic media blasting,Laser cleaning.

Q:What is the process of cap compression molding machine?

A: Compression molding is a high-pressure molding process: the polymer is melted, mixed and homogenized inside a plasticizing unit. A device draws doses of polymer that have the exact same weight as the product and inserts them into the molds. The pressure applied to each mold can be as high as 400 kg/cm2.

Q: What is the difference between compression mold and transfer mold?

A: Transfer moulding is similar to compression moulding except that instead of the moulding material being pressurized in the cavity, it is pressurized in a separate chamber and then forced through an opening and into a closed mould. Transfer moulds usually have multi-cavities as shown in Fig. 4.76.

Q: What is compression molding in simple words?

A: Compression molding is a relatively simple process involving pressing or squeezing a deformable material charge between two halves of a heated mold and its subsequent transformation into a molded part after cooling or curing. The equipment typically involves a large tonnage press (150 tons–2500 tons) and heated dies.

Q: What is the conclusion of compression molding?

A: The compression moulding process is one of the non-conventional processes in plastic engineering sector. The process is most suitable for low melt flow thermosets. The parts can possess great surface finish and strength with less warpage.
