I work as a production and mechanical design engineer
In three easy steps and under a minute you could be hosting your own AMA. Join our passionate community of AMA hosts and schedule your own AMA today.
Let's get started!
What is the most challenging part of your job?
mechanical modeling, how to choose the right dimensions so that the part would be perfect and accurate
Have you done any projects with 3d printing?
we use 3d printing to test the product before we send it to be manufactured
How do you determine the material to be used?
i depends on the quality of the part that I want and its function
Do you need special schooling to enter this field?
a mechanical engineering degree would be perfect but not enough you will have to learn even after you graduate
Do you use different types of plastics in the manufacturing process?
yes, it depends on the quality that the client wants and the function of the product, ABS is the most used material
Thank you for sharing
Hoe do you determine the layout of the mold for the product?
yes it is part of the design process of the mold
How many shots will you guarantee from my mold?
it depends on the material of the mold
What other processes do you use to create items besides injection molding?
Do you design the parts you make as well?
i design the plastic part and the mold of this part
Are you working on any current projects personally that involve injection molding or plastic part production?
yes i work now on designing a plastic case of a product
How do you insure quality?
i use the right material and the right manufacturing method and apply the right finishing methods to ensure good quality
What difficulties can appear?
How much does a mold cost?
it depends on the plastic part and how much it is going to be used
from $ 1000 to 1500
Do you design and build injection tools?
yes it is parts of my job to design molds for the products
What size parts can you make?
mostly it is small products like plastic cases for electronics
How long have you been in this field?
What made you choose to enter this field?
I am a mechanical design engineer I design everything machines, products, structures, and I do it because I love it
What advice can you give to someone starting out in this field?
some people focus on the designing part of the project but they do not know much about the production part of the project and this cause so many problems the engineer should know how to design the part and how to manufacture it
Do you mold products for a specific industry?
no, i work as a freelancer and I design products for the clients
Can you mold around inserts or metal components?
yes of course
What is the most interesting item you have made?
a plastic case of a medical device
What was it?
Do you need a Mechanical Engineering degree to do this work?
well I saw some people work in this field without a mechanical engineering degree but in my opinion, I think it is very important to have a mechanical engineering degree
Can a mold be modified if the client changes their part designs?
the mold building the final stage we do not build the mold unless we are done with designing the part and doing the final modifications
What types of parts can not be made with this process?
well in injection molding method there is a lot of considerations that we have to look at it like the part must have a draft on its surface so that we can extract the part from the mold, but some parts we must not but a draft on its surface or it will not do its job in this case we do not use injection molding
Thanks for explanation
What kind of resins do you mold?
PVC, Nylon, Nylon 32% Glass Fiber
What information do you need to quote a project?
it depends on the complexity of the project
the quality that the client wants
it also depends on my name in the market if I am a famous designer I will take more
How do you decide the type of production for a product?
it depends on the function of the product we use the right way of manufacturing for the product if we do not need the product to be perfect we use an average way of manufacturing by this way we do not spend too much money
What can someone starting out in this field expect to make per hour/year?
it depends on your skills but if you are really good you can make 100-150/hour
How do you keep up with the latest innovations in the field?
I go to fairs like MacTech
How do you keep your costs down in order to stay competitive with foreign companies?
the design must be perfect we must not use material more than we need to manufacture the part we must use the perfect amount of material that helps in reducing the cost in the long term the same thing in designing the mold
Can you injection mold rubber parts, or only plastic?
yes we can use rubber
What materials can be used to make a product with injection molding?
hello MELISSA LYNCH
these are the materials
Common thermoplastic with good impact resistance and toughness.
Thermoplastic polymer used for a wide number of applications.
Dimensionally stable thermoplastic with high stiffness and low friction.
Thermoplastic material with good temperature resistance and impact strength.
Polycarbonate / ABS
Blend of PC and ABS that creates strong parts for a variety of applications.
PVC is a polymer with good insulation properties, high hardness, and good mechanical properties.
Polymer material that is durable with high elongation and good abrasion resistance.
Nylon 32% Glass Fiber
Polymer with excellent mechanical stiffness and elevated temperature resistance.
Material with resistance to breakage often used for transparent applications.
Light weight material popular for its high impact strength and toughness.
Thermoplastic with high heat resistance and excellent mechanical properties.
