To make a good mold, not only must have a good mold design level and precision machining injection molding production process but also cannot be separated from the “standard”, which does not allow the existence of the concept of “almost”.This article lists several acceptance criteria for a good set of molds, hope it will help you.
Mold appearance
-
The nameplate of the mold is complete, with clear characters and neatly arranged.
-
The nameplate should be fixed on the injection molded foot near the template and the reference corner. The nameplate should be fixed reliably and not easy to peel off.
-
The cooling water nozzle should use a plastic block insert nozzle, if the customer requires otherwise, according to the requirements.
-
The cooling water nozzle should not stick out from the surface of the mold frame.
-
The cooling water nozzle should be processed with a sink hole with a diameter of 25mm, 30mm, and 35mm, and the hole should be chamfered and the chamfer should be consistent.
-
Cooling water nozzle should be marked in and out.
-
Mark English characters and numbers should be greater than 5/6, positioned at 10mm directly below the spout, and the handwriting should be clear, beautiful, neat, and evenly spaced.
-
Mold fittings should not affect the lifting and storage of the mold. There are exposed cylinders, water nozzles, pre-set mechanism, etc. below the installation, there should be supported legs to protect.
-
The installation of the support leg should be fixed on the mold frame with screws through the support leg, and the support leg which is too long can be fastened on the injection mold frame by turning the external thread column.
-
The size of the ejector hole of the mold should meet the requirements of the specified injection molding machine, except for small molds, which cannot be ejected with only one center.
-
The positioning ring should be fixed reliably, the diameter of the ring is 100mm or 250mm, and the positioning ring is 10~20mm higher than the base plate, except if the customer requires otherwise.
-
The mold dimensions should meet the requirements of the specified plastic injection molding machine.
-
The installation direction of the mold should be marked with arrows on the front or rear template, and the word “UP” should be written next to the arrow, the arrow and the text are yellow, and the height of the word is 50 mm.
-
The surface of the mold frame should not have pits, rust, extra rings, inlet and outlet vapor, oil holes, and other defects that affect the appearance.
-
The mold should be easy to lift and transport the injection mold parts should not be disassembled when lifting, and the lifting ring should not interfere with the water nozzle, oil cylinder, pre-reset lever, etc.

What are the types of injection mold?
There are many classification methods for injection molds. According to different classification bases, injection molds can be divided into different types. This article will classify injection molds in detail according to different classification bases. I hope to provide some help for you to further understand injection molds.
What are the three different types of metal molds?
The three different types of metal molds are injection molds, blow molds, and compression molds. Injection molds are used for creating complex shapes by injecting molten metal into a mold cavity. Blow molds are mainly used for hollow objects, where air is blown into a heated plastic to expand it into the mold. Compression molds involve placing a material in a heated mold cavity, where it is then compressed to form a specific shape, commonly used for thermosetting plastics.
What are plastic injection moulders used for?
Plastic injection molding is a process for producing parts by injecting materials like metals, glasses and thermoplastic, into mold cavity. Injection molds are used to make things like bottle caps, mechanical parts, automobile dashboards and packaging.
What material is used to make a stapler?
A stapler is composed of mostly aluminum sheet metal, cut and pressed to function, and plastic injection molds.
Where can I purchase injection molds online?
Injection molds are usually made to the specifications of the user and there are numerous books and DVDs sold that tell you how to do this. One place that will make injection molds for you on quick turnaround is: http://www.quickparts.com/ToolingProduction.aspx
What are standards for blow molds?
Standards for blow molds typically focus on areas such as material quality, dimensional precision, design specifications, and production consistency. They help ensure that the blow molds are suitable for producing high-quality plastic components with consistent results. Compliance with standards also helps facilitate interoperability and interchangeability across different manufacturing processes and equipment.
What are the main uses of injection molds?
Injection molds are used when making products with the manufacturing technique "injection molding", meaning that they are molds that you inject materials such as glass, metals, and other kinds of fluid materials into, and then cool it off to get the finished product.
How can I make hard plastic molds?
To make hard plastic molds, you can use a process called injection molding. This involves melting plastic pellets and injecting them into a mold cavity, where they cool and harden to form the desired shape. The mold can then be opened to release the plastic part. This process requires specialized equipment and expertise, so it is recommended to work with a professional mold maker or manufacturer.
Who uses injection molds and what can they make?
An injection mold is a closed mold where the material to be molded into that specific design is fed through a fill hole in the mold. This is a common process for plastic goods but is also used for cars' body panels.
