Questions And Answers about Injection Moulding

Does injection moulding have an environmental impact?

The use of thermosetting polymers and more efficient machinery is allowing injection moulding to become more eco-friendly, while materials are capable of enduring extreme temperatures and conditions.

Injection molding produces a small amount of waste material in comparison to many other manufacturing processes. In addition to how long the materials last, whether they can be recycled, and how they are disposed of, the specific materials used also have an environmental impact. In addition, a carbon footprint must also be considered over the lifetime of the product, including its manufacture.

Injection molding machines today use between 20 and 50% less energy than they did ten years ago due to advances in technology.

Approximately how much does injection molding cost?

Using the following formula, you can calculate the exact cost of injection molding:

Material costs + design + production + profits + tax + try-out costs + packing and shipping costs = mould price.

Material and part costs represent 15-30% of the total, and process and profit represent 30-50%.

However in the Injection molding Company, the injection molding tools are expensive, but the actual process is relatively inexpensive.

Injection molding uses what kind of plastic?

More than 85,000 commercial plastic material options and 45 polymer families are available for injection molding. A polymer can generally be divided into two groups; thermosets and thermoplastics.

Low-density polyethylene (LDPE) and high-density polyethylene (HDPE) are the most commonly used plastics. Polyethylene is an overview of the best injection molding China is known for its high ductility, high strength, resistance to impact, and recyclability. The Chinese have many mold injection companies. Here is the best Injection molding China you can choose.

Injection moulded plastics are also commonly used for:

1. Polycarbonate (PC)

Plastic that is strong, impact-resistant, and dimensionally stable. In addition to being transparent, PC can provide good heat resistance and a high cosmetic finish.

2. Acrylonitrile Butadiene Styrene (ABS)

In industry, this tough, impact-resistant plastic is widely used. ABS offers a low shrinkage rate and high dimensional stability in addition to being resistant to acids and bases.

3. Aliphatic Polyamides (PPA)

Each type of PPA (or nylon) has its own advantages. Overall, nylons are high-strength, temperature-resistant, and chemically resistant, except for strong acids and bases. Several nylons are abrasion-resistant and have good hardness, stiffness, and impact strength.

4. Polyoxymethylene (POM)

Acetal is a plastic that is hard, stiff, strong, and tough. It is also lubricious and resistant to hydrocarbons and organic solvents. Good elasticity and slipperiness provide additional advantages.

5. Polymethyl Methacrylate (PMMA)

Acrylic, also known as PMMA, has good optical properties, a high gloss, and is scratch resistant. In addition, it offers low shrinkage and less sink for geometries with thin and thick sections.

6. Polypropylene (PP)

When cold temperatures are present, however, this resin material can become brittle (most notably when it is propylene homopolymer). A copolymer is more resistant to impact, while PP is wear-resistant, flexible, and can provide very high elongation, as well as being resistant to acids and bases.

7. Polybutylene Terephthalate (PBT)

Because of its good electrical properties, PBT is ideal for power components and automotive applications. Grades with glass fill can range from moderate to high strength, while unfilled grades are tough and flexible. Besides fuel, oils, fats, and many solvents, PBT also doesn’t absorb flavors.

8. polyphenylsulfone (PPSU)

Dimensionally stable, PPSU is also heat and radiation-resistant, resistant to alkalis and weak acids, as well as dimensionally stable.

9. Polyether Ether Ketone (PEEK)

In addition to its high temperature and flame retardancy, this resin has good dimensional stability, strength, and chemical resistance.

10. Polyetherimide (PEI)

In addition to its high-temperature stability and flame retardancy, PEI (or Ultem) is also strong, dimensionally stable, and chemically resistant.
