key technical points to making Microwave container mold
Creating a microwave safe plastic container mold is a crucial process that requires attention to detail. The following are key technical points to consider when making such a mold.
Choose the right plastic material: Not all plastics are microwave safe. It is crucial to select a material that is approved for use in the microwave and can handle the high heat of the oven without melting or deforming.
Design an airtight seal: A proper seal on the container is essential to prevent any leaks or spills. This involves designing a tight-fitting lid that snaps on securely.
Consider the size and shape: The mold should be designed to produce a container that is the right size for the microwave and the user's needs. The shape should avoid any corners or sharp edges that could cause the plastic to warp or melt in the microwave.
Add ventilation: When designing the mold, it is essential to include small holes or vents in the container's lid. This allows steam to escape and prevents the plastic from becoming distorted.
Test the mold before production: Before mass producing, it is essential to test the mold to ensure the containers' quality and safety. Checks should include size, shape, lid seal, and microwave performance.
Producing a microwave safe plastic container mold is a careful process that requires attention to detail. Following these technical points will ensure a safe and effective container that can efficiently heat food in the microwave.
Plastics are used in Microwave container
These containers are popular for heating and storing food due to their convenience, durability, and ability to withstand the heat generated during microwaving. However, not all plastics are microwave-safe, so it's essential to choose the right type of plastic to avoid safety risks.
- Polypropylene (PP): One of the most common plastics used for microwave containers. It's durable, resistant to heat, and doesn't leach harmful chemicals when heated.
- Polyethylene (PE): Low-density polyethylene (LDPE) is also commonly used for microwave-safe containers, though it can warp at high temperatures.
- Polycarbonate (PC): Formerly popular, but now less common due to concerns about bisphenol A (BPA) leaching, especially at high temperatures.
- Polyethylene Terephthalate (PET): PET is not typically recommended for reheating in microwaves as it can melt at high temperatures.
Microwave container Mold Design Guide
1. Mold Material Selection
The materials of the mold need to have properties such as high temperature resistance, pressure resistance, and corrosion resistance, because they need to withstand the high temperature and heat involved in the production process of microwave containers.
- Steel (such as P20, H13, etc.): One of the common mold materials, with good hardness and durability, suitable for the production of plastic, PP (polypropylene), PE (polyethylene) and other containers. Especially suitable for mass production and can withstand high temperature and high pressure.
- Aluminum alloy: Lightweight and good thermal conductivity, suitable for precision mold manufacturing, especially when rapid cooling and heating are required.
- Thermosetting materials (such as aluminum, copper, nickel alloys): Suitable for container molds with complex shapes, especially when the container is designed with multiple small compartments or unique shapes.
- Mold steel (such as S136, 718H, etc.): These steels can extend the service life of the mold when producing microwave food containers due to their good corrosion resistance and wear resistance, especially suitable for high-frequency and large-scale production.
2. Mold design options
The design mainly considers the functional requirements of the container and the efficiency of the production process. Common design options include:
- Single-cavity molds: Suitable for low-volume or complex custom container designs. It can produce single-shaped and more customized containers.
- Multi-cavity molds: Container mold design suitable for mass production, which can produce multiple containers of the same shape at a time to improve production efficiency.
- Divided design:
If the customized container has multiple partitions (such as lunch boxes, meal boxes, etc.), the mold design needs to consider the precision of the partitions. Divided molds usually have multiple small partitions or raised parts to form these partitions.
- Complex shape and chamfer design:
Microwave food containers often have shape requirements, such as round, square or curved edges. When we customize the mold, we need to accurately calculate and design to ensure that these complex shapes can be accurately manufactured.
3. Container design requirements
Depending on the actual use of the container, the following points need to be considered when designing the mold:
Container size and capacity:
When customizing the mold, the size and capacity of the container must be accurately calculated. This usually requires designing the height, width, depth, etc. of the container according to the food storage requirements.
Lid mold design:
If the food container needs to have a lid, the lid mold design is also very critical. The lid needs to seal well and not produce excessive pressure or deformation when heated in a microwave. Therefore, the lid design needs to take into account sealing and ventilation holes.
markets of Microwave container Mold
1.Household and personal consumption
With the popularity of fast-paced lifestyles, more and more people tend to choose to heat food in microwave ovens. This has led to an increase in the demand for food containers suitable for microwave ovens, especially single-serving or multi-functional containers, such as compartmentalized lunch boxes, heated lunch boxes, etc., which have become popular choices in home kitchens and takeaway catering markets.
2.Catering takeaway
The takeaway industry has developed rapidly, especially during the epidemic, when the demand for catering takeaways has surged. This has prompted merchants to increase demand for microwave-safe food containers, especially those that can keep food fresh, heat evenly, and not leak. Customized containers for takeaway brands can enhance brand image and improve customer experience.
3.Pre-prepared meals
With the increase in work pressure, more and more people choose to buy pre-prepared meals, especially frozen and quick-frozen meals. For this market, customized microwave-safe food containers are particularly important, because the containers must not only be resistant to low and high temperatures, but also ensure that no harmful substances are released after heating.
4.Cold chain logistics:
The transportation and storage of cold chain food requires containers to have good freshness preservation and heating capabilities, so higher requirements are placed on the container's high temperature resistance, sealing, and heating uniformity.
5.Food Processing and Wholesaling
For food processing companies and wholesalers, custom microwave food containers can help improve product packaging standardization and brand recognition. For example, bulk packaged foods can be eaten directly after being heated in the microwave, and customized containers can meet this demand.
FAQ
Q: What happens if you eat food that was microwaved in plastic?
A: When food or beverages are microwaved in plastic containers, chemical additives from inside the plastic migrate into the food and tiny flecks of plastic known as micro- and nanoplastics are also shed into the food. Both of these can present health risks.
Q: Can I microwave a plastic bowl?
A: Microwaving provides enough heat to degrade or even melt certain types of plastic. For these reasons, follow USDA guidelines and only use clearly indicated "microwave safe" plastic containers that have been labeled accordingly.
Q: Is it safe to eat food that sparked in the microwave?
A: An arcing effect is when sparks occur as a result of electromagnetic waves in a microwave reflecting or bouncing off metal. On the plus side, the arcing doesn't cause any damage to the food. But the bummer is that it does prevent food from being thoroughly heated through.
Q: Is it safe to put hot food in a plastic bowl?
A: Bisphenol A, also known as BPA, is used in all sorts of plastic containers, cans, feminine hygiene products, toiletries and many other products. In the case of food, when such containers are heated, the chemical leaches into your food, making it toxic.
Q: What bowls are not microwave safe?
A: Materials Unsafe in the Microwave Cold storage containers (such as margarine tubs, cottage cheese, yogurt cartons). ... Brown paper bags, newspapers, and recycled or printed paper towels. ... Metal, such as pans or utensils. Foam-insulated cups, bowls, plates, or trays. Stones, including massage stones.
