    Ways to take the molding plastic sheet out of the plastic mold

    The process of taking the product out of the plastic mold in fact requires quite high technical requirements.?Ways to remove the product from the plastic mold include:

    Manually remove the product from the plastic mold

    This is the most common method applied at plastic injection companies in USA.?Workers will directly take the product out and then inspect and cut the bavia after completing each pressing cycle. The manual picking method offers great advantages in the case of large products where the push-pull system is difficult to use.?Besides, there are still many limitations:

    • Workers when taking products out of molds need to strictly follow the principles of labor safety.
    • Mold design quality is easy to affect due to the mold taking operation performed
    • Manually removing molding plastic sheetfrom molds is time consuming and labor intensive.

    Remove the product from the mold using the robotic arm

    Removing the product from the mold by using a robotic arm requires high investment costs.?However, this brings long-term benefits; automation greatly increases the productivity and efficiency of plastic injection.

    The robot arm is pre-programmed for molding plastic sheet?out of the mold quickly and accurately, the reduction of bavia is good to use via the manual method.? Each plastic injection machine comes with an automatic robotic arm; the working process is fast and extremely efficient.

    Push system to take the product from the mold

    The product ejection system from the mold includes the following ejection systems:

    • Using push pin: is the most common system common when designing plastic injection molds.?
    • The push system is particularly effective for large, thick-walled parts.?Using push blade: commonly applied in pushing thin-walled parts, complex shapes and structures.
    • Using push tube:mainly applied with round plastic parts.
    • Moreover, using the release plate:common for cylindrical or rectangular shaped parts with thin wall thickness
    • Using compressed air:Basically, it is suitable for production of products with deep cavity.

    Depending on the technical requirements, shape and size of the product, the design unit offers the most suitable and effective propulsion system.

    Learn how to make plastic molds

    We are a reputable unit in the field of?molding plastic sheet. We are a prestigious and reliable company. Similarly, we provide the entire process and comprehensive solutions in plastic product processing.?Let's learn together about how to make plastic molds in the article below.

    Learn about plastic molds

    All plastic products are common in daily life. Similarly, we get the parts from plastic molds.?Different types of plastic products will have different mold shape and texture requirements. Moreover, a plastic mold is a tool for shaping plastic products.

    Moreover, this consists of many parts that fit together. In addition, liquid plastic injects into it and then cooled, to get the required product shape and moves out from the mold.

    In the entire system of operating machinery to produce plastic products, plastic molds play an extremely important role.?A mold with the correct structure and specifications appears. This will help the machine system operate smoothly and efficiently for molding plastic sheet. Thereby producing good quality plastic products with beautiful designs is easy.

    Learn about designing and making plastic molds

    The design and?manufacture of plastic molds?plays an extremely important role in the entire production process of plastic products. Furthermore, this requires strict technical and professional qualifications.

    Plastic mold design

    The plastic injection mold design come with detailed molds such as:

    • mold shell design
    • mold core details and
    • Moreover, mold components... so it needs to implement absolutely accurate.

    The design must provide the viewer with full details of each item to manufacture, such as projection angles, dimensions, cross-sections, tolerances that need to meet technical requirements...

    How to make and produce plastic molds

    In order to?molding plastic sheet?that meets technical requirements with an accuracy of up to 1/100 mm, the mold must be according to a strict process. Molding material is an extremely important factor. The main material common to make the mold is different types of steel with high strength, good bearing capacity. It is to ensure a smooth, continuous plastic injection process.

    Plastic mold making?is an activity that plays a prerequisite role in the production of plastic products. This is a significant determinant of product quality to consumers.

    Process of molding plastic sheet

    The manufactured molding plastic sheet?will consist of 2 halves:

    • one half with many parts and components
    • the other half come at certain precise positions so that the upper bar fits into the hole

    This helps the 2 halves to match. Together completely and form a mold shape when plastic poures.

    The steel b lock that is forming the mold is then put in and carried out to remove the rough surface; this is considered an extremely necessary processing step to turn the steel block into a mold.

    How CNC machine is controlled?

    The CNC machine controlled from the computer will perform machining, the steel block is slowly abraded, and we will get the shape of each part.?This CNC machine proceeds to create copper electrodes with the same design as the plastic parts that the business wants to produce.

    After the copper electrode is polished, the electrolysis process begins, before that; the electrode has been brought down to contact the molding plastic sheet.?Next, using a high-intensity electric current flowing through the copper electrode, after printing on the mold, we will get the desired shape on that half of the mold.

    Why mold is polished?

    After the mold is processed, the mold is polished to remove the rough surface, increase the gloss and brightness, and produce a finished, high-quality plastic mold product.

    In addition, in the manufacturing process, it is necessary to carry out an additional step of reverse engraving in the mold for the purpose of printing the manufacturer's label and brand on plastic products.?After the plastic product is completely molded, pushed out, we will have real and embossed text on the surface of the product.?
