2. Types Of Plastic Spoon Mould
There exists several types of plastic spoon mould depending on what you are looking for. These types include:
- Face mounted
These types of plastic spoon mould features single cavities mounted on top of an aluminum plate. They are then attached by screws using special tools called faceplates.
- Gravity feed
This style is for spoon that have a simple design. This type of plastic spoon mould is suitable for spoons that do not require any additional inserts or secondary operations.
- Insert molding
This type of plastic spoon mold is best suited for items that need secondary operations and additional inserts.
The moulding tool consists of a core and cavity. These two parts are held together by screws on to the main plate.
Once it is removed, you have access to both sides of the mould. This way you fill the mould with material or get rid of any waste inside.
Single cavity
This is simply a plastic spoon mold that produces one item at a time.
- Multi-cavity type
These types consist of multiple cavities and is used for mass production.
Multi Cavity Plastic Spoon Mould
- Injection blow molding type
This is a type of plastic spoon mold where the material is blown into the mold.
3. Parts Of Plastic Spoon Mould
The major parts of a plastic spoon mold are as follows:
Cavities
There are moulds with single or multiple cavities. A cavity is basically the area of the mold where the item is formed to the desired shape, in this case spoon shaped.
Cavities Of A Plastic Spoon Mould
Cooling system
The plastic material is usually injected hot then cooled by a cooling system which allows conduction to cool the part.
The cooling fluid is usually water. However in some cases oil can be used in high temperature applications.
Feed system
The plastic material flows through here and then to each runner which in turn take the material to the gates. The gate is basically the point of entry of the material to the individual cavities.
4. Materials For Making Plastic Spoon Mould
Plastic spoon mould can be made out of the following materials:
- Aluminum
Aluminum is suitable for making plastic spoon moulds because of its light weight nature and high strength. This material is also best for producing high-volumes of plastic spoon shaped items.

- Stainless steel
Stainless steel is highly resistant to wear and corrosion. It is therefore best to use it where there are such risks. This material exhibits a certain level of hardness which makes it best for producing high quality and long lasting items.
- Zinc
Plastic spoon mould can be made from high conductivity Zinc. This material has a high dimensional stability as well as high rigidity. These properties make the plastic spoon mould have an excellent surface finish. Zinc is highly resistant to corrosion, therefore making moulds and parts made by this material very long lasting.
- Glass filled polypropylene
This material is perfect for plastic spoon moulds that come into contact with food. Glass filled polypropylene has an excellent dimensional stability as well as surface finish. This material has other features such as high stiffness and wear resistance. This makes it most suited for large plastic spoon moulds with thin walls.
- Polycarbonate
Polycarbonate has a lot of great features as a material for making plastic spoon moulds. It is resistant to impact, corrosion resistant and also UV stable. It also has a high stiffness as well as a very good surface finish. This properties makes polycarbonate an ideal material for big plastic spoon moulds.

- Acetal POM
This material is used on plastic spoon moulds that require high wear resistance. For instance the pharmaceutical and food industries.
It has an excellent surface finish quality and dimensional stability. This material however, is not recommended for spoon moulds that have to deal with moist conditions. Acetal is also not suitable for moulds that come in contact with food.
5. Factors Affecting Cost Of Plastic Spoon Moulds
Cavities
The higher the number of cavities translates to higher productions costs. Few or single cavity molds do not require a lot of time or tooling thus lower production costs.
Mold material
This is such a crucial cost consideration in plastic spoon moulding. The material of the mold can affect the overall cost significantly.
For instance, aluminum molds are relatively cheaper compared other materials such as steel. Less expensive moulds are suitable for short production runs.
Size
Large moulds have high costs as they need large parts and components. They also use more material to make which drives their price up.
6. Steps In Plastic Spoon Moulding Process
The plastic moulding process involves the following steps:
- Clamping
- Injection
- Dwelling
- Cooling
- Opening stage
- Ejection
7. Industries Using Plastic Spoon Moulds
Plastic spoon moulds are used across several industries including:
- Food industries
- Medical industries
- Packaging industry
Spoons Made For Food Industries
8. Suitable Materials For Plastic Spoon Moulding
PP (Polypropylene)
This is the most commonly used material for manufacturing plastic spoons. It is actually the ‘industry standard’ for plastic spoons. This is because PP has very good and useful properties.
For instance, it has a high stiffness and excellent mechanical properties. This material has a certain level of toughness that allows for easy processing in the plastic injection machine.
PP is also such a suitable material because of its easy sterilization. It can be exposed to certain gases without undergoing any significant changes.
A Polypropylene Spoon
PC (Polycarbonate)
PC or polycarbonate is another common material for plastic spoon moulding. It is high in strength, impact resistance and exhibits good chemical resistance.
Another factor that makes PC a suitable material for plastic spoon molding is you can use it in a wide range of temperatures. This ranges from -30 TO 70 Degrees Celsius.
PE (Polyethylene)
This is yet another common material for plastic spoon moulding. It is a very stiff and tough material. It also has an excellent chemical resistance making it very easy to process in the injection moulding machine.
Polyethylene Spoon
Just like PP it can withstand being exposed to certain chemicals for sterilization without experiencing any significant changes.
ABS (Acrylonitrile Butadiene Styrene)
This material is most suitable for the medical industry. It exhibits high strength as well as toughness. ABS has a relative stiffness that allows it not deform easily. ABS can be quite expensive compared to PP and PE.
9. How To Maintain A Plastic Spoon Mould
Maintaining your mould can help it reach its full lifespan potential thus saving you time and money. The following are ways in which you can take care of your mold:
- Regular inspection
Carrying out regular inspection on your mould can highlight any problems or inconsistencies that may go unnoticed during day to day use.
Then you can schedule repairs or replacements before the issues get out of hand. Most manufactures provide a guide on the procedures of the inspection and how often they should be done.
- Regular maintenance
Servicing a plastic spoon mould regularly can help avoid major issues. Maintenance can be as simple as cleaning after use or lubricating parts to avoid wear.
Always ensure to remove any excess material to avoid buildup. It is also important to use the manufacturers recommended solutions when cleaning.
The same goes for lubrication. Use the recommended lubricants.
Maintenance also includes protecting your mold from corrosion. You can use anti corrosion spray to protect it from this risk. Minimizing exposure to moisture can also help your mould stay for longer without corroding.
- Correct storage
You should store your mold in a cool, dry space. Most plastic spoon moulds are not weatherproof so do not store them outdoors. For smaller moulding machine ensure to place them in visibly to prevent it from being damaged or lost.
- Part replacement
It is essential to replace worn out or damaged parts to keep your plastic spoon mould running smoothly. Changing as soon as possible can prevent further damage or wear of other parts.
You can keep a stock of parts that wear regularly and replace as needed.
10. Causes Of Wear In Plastic Spoon Moulds And How To Avoid Them
The most common causes of wear in plastic spoon molds are:
Corrosion
Corrosive wear is can be caused by chemical reactions. Corrosion is usually caused by moisture and can be in the form of either rust or oxidation.
To prevent corrosive wear, you can treat your mold with anti-corrosive sprays. You can also avoid exposing them to moisture.
Friction
This type of wear can be as a result of parts touching or sliding against each other. You can avoid friction by lubricating parts properly and regularly.
11. Common Defects In Plastic Spoon Moulding
During the plastic molding process you can encounter the following defects:
- Voids
Voids are also known as air pockets. They are more likely to occur in the thicker areas of the molded spoons.
Voids come about when the surface cools down faster and solidifies quicker that the inner material.
The inner material shrinks as it cools down. If it is not able to shrink fully, the molecules of the material pull apart thus forming voids.
To avoid having voids in your item, make sure there are no unnecessary thick in your plastic spoon design. Also ensure to dry the material completely as moisture can also be a cause of voids.
Void Defect
- Sink marks
This defect can be described as a depression that appears on the surface of the molded item. Sink marks are usually caused by uneven cooling of the material.
During the cooling process, the outer surface of the material cools faster than the inner. This means the outer surface solidifies first.
When the inner surface starts to solidify, it shrinks thus pulling in the outer surface which is already solid.
You can prevent sink marks from forming by ensuring that you keep the wall thickness uniform at all times. Another way is to reduce the injection temperature of the material as well as the mold.
- Burn marks
This defect appears on the finished product a discoloration which is dark in color. Burn marks are caused by trapped gas overheating in the mold. They can also be caused by excess heat or the speed of the injection being too fast.
To prevent burn marks, reduce both the injection speed and pressure. Also ensure that the mold has sufficient air vents to let the excessive gas escape.
- Flow lines
Flow lines, also known as streaks occur on the surface of the finished item. Some people overlook this defect while others do not as it can be aesthetically not pleasing. Flow lines appear when the molten material flows at different speeds throughout the cavity and the change in direction. Flow lines appear as the plastic begins to solidify at different speeds.
Flow Lines defect
To avoid having this defect on your finished part, increase the speed and pressure of the injection process.
You can also make sure to increase the temperatures of both the mold and molten plastic throughout the injection process.
