    Essential Tests for Export Mold 

    What tests need to be done before an injection mold is exported?
     
    ✅ Mold Appearance: As per customer signage, located on the operator's side.
    ✅Mold Transportation: Ensure the lifting holes of each template are centered.
    ✅Mold Assembly and Disassembly Mechanism: Tight-fitting inserts or components should have removable threads or holes.
    ✅Pouring System: Specifications for the diameter of the positioning ring.
    ✅Cooling System: Water pressure test should show no leaks.
    ✅Ejection System and Reset: Ejection should be smooth, without jamming or unusual noises.
    ✅Slider Mechanism: The fixed slider inserts should not wobble sideways.
    ✅Inclined Ejector Mechanism: Parts of the inclined ejector mechanism should be marked with codes.
    ✅Cavity and Core: According to drawing requirements, the hardness values of the cavity and core must meet standards.
    ✅Inserts and Pins: Inserts/pins should be assembled tightly and not be too loose to fall freely.
    ✅Hot Runner System: The inner cavity should have rounded transitions, with no sharp corners.
    ✅Oil Cylinders and Air Cylinders: Oil and air cylinders should have positioning safety devices.
    ✅Other Components: The bottom of the guide sleeve should be designed for venting.

    Plstic Injection Mold FAQs

    • Q1: What is plastic injection mold?

       A: Plastic injection mold is a specialized tool used to shape molten plastic into specific forms, allowing for high-precision production of plastic parts. It's used across a wide range of industries including aerospace, medical devices, consumer goods, energy, electronics, automotive, robotics, security, toys, and more.

    • Q2: Why do plastic injection molds cost so much?

      A: Plastic injection molds can be expensive, typically ranging from $2,000 to over $100,000, depending on complexity and size. For example, a simple mold for a small part might cost around $2,000, while a complex mold for automotive components could exceed $50,000.

      Plastic injection molds can be expensive due to several key factors:

      Quality of Materials: High-quality molds are constructed from premium metals, such as aircraft-grade aluminum or hardened mold steels, which are essential for producing durable and precise parts.
      Skilled Labor: Mold makers are highly skilled professionals who often spend years, if not decades, honing their craft. Their expertise is crucial for designing and manufacturing effective molds.
      Advanced Tools and Technology: Mold makers require expensive tools, including specialized software, CNC machinery, and precision fixtures, all of which contribute to the overall cost of mold production.
      Complexity and Size: The time required to create a mold can vary significantly, ranging from a few days to several weeks, depending on the complexity and size of the end product. More intricate designs naturally increase the time and effort involved.

    • Q3: Who owns the tool?

      A: At Alpine Mold, our customers own their injection mold tools! After a run is complete, the tool will remain at our facilities. Tools can be shipped to you upon request; however, you will be responsible for any associated shipping and packaging costs. Our engineers will work with you regarding tool compatibility with your equipment if you're unsure.
