Problems with the law regarding plastic injection parts If you have any newly developed plastic parts that need to be evaluated further by our plastic injection molding service, please contact Pan Taiwan right away. A Pan Taiwan sales representative will follow up with you within a day!

You probably already know that plastic injection molding is a quick and effective method for mass producing plastic products like furniture, food containers, retail packaging for beauty products, and toys. Any common plastic item you come across probably comes from this manufacturing process. In order to create a molded part, molten plastic is injected into a metal mold at high speed and pressure before cooling and solidifying to take on the mold’s shape.

As a buyer, what do I do?

Before you decide to purchase plastic injection moldings, you need to know that doing so necessitates a deeper involvement in the process. For instance, if you are sourcing a molded part that is particularly intricate, you may need to be involved in its design. There are various plan choices you really want to take as these will decide your plastic infusion shaping cost and quality. It is essential to make well-informed decisions early on because doing so will assist you in locating and resolving potential issues. 

The first step in purchasing a custom plastic injection molding is for you, the buyer, to provide the supplier with detailed 2D drawings of the part’s material type, surface finish, tolerances (the acceptable amount of dimensional deviation), and any particular critical dimensions. We will act as a middleman if you use a sourcing agent like Sourcing Allies. The most widely accepted STEP or IGES formats are preferred by most suppliers. In collaboration with your supplier and sourcing agent, you can make any necessary adjustments to your initial design.

When purchasing plastic injection moldings from a plastic mold manufacturer in China or anywhere else, one thing to keep in mind is to be very specific with your supplier about your requirements, including price, quality, lead time, and other factors. It’s also a good idea to write everything down.

Why choosing the right material is important 

One of the most important choices a buyer must make before making a purchase is choosing the right plastic raw material. All things considered, the strength, sturdiness, adaptability, usefulness, appearance, and cost of the part all rely on this decision. This is not an easy choice to make because there are over 85,000 different kinds of plastic. Yet, you can begin by really getting to know the most famous plastics utilized in plastic infusion shaping and their properties:

Styrene made of acrylonitrile butadiene (ABS): It solidifies quickly, resists impact well, is strong and durable, appears glossy, and does not easily shrink when molded. Parts like pipes, toys, and golf stick heads made of ABS are light and rigid. However, it is unsuitable for use in parts that are subjected to prolonged and intense heat because it melts or warps at temperatures above 93 degrees Celsius. 

PC: Polycarbonates These are a gathering of hard, firm, and intense thermoplastics that are likewise known for their warm soundness. Polycarbonates are used to make safety goggles, riot shields, compact discs, baby bottles, and other items due to their inherent transparency. However, they are not ideal for products that require color aesthetics or a certain degree of flexibility.      

PP, or polypropylene, Products that are lightweight, heat- and water-resistant, flexible, and pliable are made from this thermoplastic. Examples include toys, pipes, cables, bottle caps, washing machine drums, and food packaging. Additionally, it can be spun into fiber for rope, carpet, and upholstery. Due to its versatility, polypropylene is frequently referred to as the “steel of plastics.” Nonetheless, it is hard to color or paint, is inclined to UV debasement and is combustible.      

Nylons: Nylons are a class of plastics that are resistant to heat, chemicals, and wear. They are also flexible, long-lasting, and flow easily around complex inserts. Nylon molded parts include food packaging, fasteners, and toothbrushes. However, shrinkage is a problem with nylons. Additionally, they lack heat resistance, water absorption, and dimensional stability.

Acetal: This tough, stiff thermoplastic is easy to machine, has good wear resistance, and has high dimensional stability. Additionally, it resists friction well, can be dyed easily, and is affordable. Acetal can be molded into valves, zippers, and heads for garden hoses. Products that will be used in environments where they are exposed to acids, UV rays, and high temperatures should not be made of this plastic.

Polyethylene (PE): Polyethylene is ideal for waterproof molded parts due to its resistance to moisture. Think shopping bags made of plastic. Additionally, it is affordable, soft, flexible, and lightweight. Both a high-density and a low-density version are available. Six-pack rings, containers, and computer parts are all made of low-density polyethylene (LDPE). It should not be used in extreme temperatures or weather. High-density polyethylene (HDPE) can be used for a wide range of applications, including common ones like pipes and lotion bottles.                  

Keep in mind that picking the right material doesn’t end with choosing the right plastic. You must be aware of the ideal molding conditions for your product and material as a buyer. This includes the temperature and pressure of the injection, the mold, the temperature of the ejection, the cooling time, and the cycle time. Draft angles and undercuts—more on these in the following section—are also important to be aware of because plastic injection molded parts are becoming increasingly complex. Naturally, all of these decisions need to be made early to avoid stress during and after production, additional costs, and delays.
