Plastic mold technology is also known as plastic molding (or molding) technology which is a process
that has been around since 1872, it is the process of creating and manufacturing plastic components by
injecting molten materials into a plastic mold. The process of plastic molding technology is actually quoted as
a complex one. First, the part designer needs to design the desired model or hire your supplier to design the
model according to your requirement, then mold designer must come up with a completely final mold design.
Once this has been created, then start to manufacture the mold, like drilling, CNC machining, EDM, polishing
and the last step to make the mold is mold fitting, when everything is finished in mold making, that the actual
the injection molding process can start, at the beginning of the molding process we called mold trial, from mold
trial to massive production, this still need to take some time, because the first mold trial will more or less have
some issue needs to be finished, after two or three-time mold trials until custom approval the samples, so we
could start massive production, this is a simple idea to explain from part design to the ending plastics product.
Although plastic molding technology is not something that most will be knowledgeable about. We all use
products that will have been manufactured by using this method. Things like bottle caps, automobile parts,
home appliances, furniture components & accessories, bicycle accessories, cosmetics molding & packaging
containers, cooking equipment, toys, medical parts, and construction part, etc. We can say everything
needs plastic molded parts.
What are the types of Moulding?
Molding or molding (see spelling differences) is the process of manufacturing by shaping liquid or
pliable raw material using a rigid frame called a mold or matrix.  This itself may have been made using a
pattern or model of the final object.
There are several types of molding methods.
Powder metallurgy plus sintering
Reaction injection molding
Rotational molding (or Rotomolding)
Vacuum forming, a simplified version of thermoforming
What is mold flow analysis?
Mold flow analysis is the process of simulating an injection molding cycle with a particular plastic and
analyzing the results. Mold flow analysis should occur before the injection molding process ever begins,
through the use of specialized software that simulates the design of the part to be manufactured. Since the
flow of the liquid material in the mold makes a massive difference to the behavior of the product, this step can
save a great deal of effort down the road. This software creates color maps of different properties of the
design as they would be reflected in the actual mold flow. These may include heating/cooling, fill pattern,
injection pressure, potential air traps, shear stress, fiber orientation, and many more properties. Mold flow
analysis is a careful, hands-on-process meant for experts.
The color maps created by mold flow analysis assist in adaptive changes of the design in order to create a
quality product before the molding process actually occurs. This ensures that when a prototype or product
goes into production, it is going to perform and behave optimally.
