There are a wide variety of molding machines, such as CNC machining, EDMs, drilling and milling equipment, etc. The molding machines have different working mechanisms and are used for different purposes. Due to that, it is best to choose the proper machines that are compatible with the type of products the business will produce. Avoid picking cheaper molding machines, as they may stop working in a few months. Choose durable and good-quality equipment.

If you need an electronics housing or similar box-shaped part, you can either sink the wall cavities deep into the mold base, requiring long thin tools to machine ribs into the mold, or machine the aluminum material down around the core and mold the part around it. The latter approach is known as a core cavity, and is a far more cost-effective method of molding tall walls and ribbed surfaces. Better yet, this makes it easier to provide smooth surface finishes, adequate venting, improved ejection, and can eliminate the need for super-steep draft angles.

Based on the total cavities in the molding tool, the injection molding procedure can create plenty of components in an hour. With the proper molding tool design and molding equipment, it is possible for businesses to consistently create high-quality parts with shorter lead times.

Estimate the entire costs of setting up the injection molding business, including the equipment cost, tooling cost, factory cost, labor cost, etc. After estimation, decide on the price of the injection molded products to ensure that the costs are recovered by the revenue.

The market of plastic injection molding is relatively broad as injection molded products are produced for various industrial applications. The revenue of the injection molding business market in 2020 stood at USD 343.23 billion and reached USD 357.34 billion in 2021. As per the market estimations, the global injection molding plastics market is analyzed to thrive at USD 476.46 billion by 2028.

Pretty parts are nice, but they often require bead blasting, EDM, or high mold polish to achieve an elevated level of cosmetic appearance. This drives up tooling costs. Anything greater than a PM-F0 (as machined) finish requires some level of hand work, up to an SPI-A2 mirror finish using Grade #2 diamond buff. Avoid fine finishes such as these unless they’re required for the job. One thing to consider regarding cosmetics is to let Protolabs know if you need the entire half of the mold polished or maybe just one small area. You could save costs by only polishing the area needed versus the entire side of a mold. When requesting a custom finish, just send Protolabs a color-coded image of the critical areas and desired finish level for each area.

Injection molding businesses will ensure that the business owners get enough profits. Since the demand for these products is increasing, the injection molding business will have more than enough clients, so the manufacturing process runs throughout the year. This way, it will be easy to earn more revenue.

Textured surfaces, molded part numbers, and company logos look cool, but be prepared to pay a bit extra for these and other non-mission critical features. That said, permanent part numbers are a requirement for many aerospace and military applications. Use a mill-friendly font such as Century Gothic Bold, Arial, or Verdana (san-serif fonts), keep it above 20 pt., and don’t go much deeper than 0.010 to 0.015 inch. Also, be prepared to increase draft if part ejection is a concern.

The injection molded parts are made using high-quality medical-grade materials that are known for their sturdiness and long-lasting features. Due to that, injection molding medical devices last for a long period, stay durable, and can withstand heavy pressure and temperature. The molded products are highly used in applications that require impact resistance, pressure resistance, temperature resistance, etc.

The present plastic injection molding businesses are producing a wide range of products for different industrial niches. For example, the various niches include the pharmaceutical field, medical device field, automotive field, telecommunication field, electronics, food and beverage industry, packaging industry, construction field, and many more. As there are many niches for injection molding, it is vital to choose a specific niche. This way, one can establish a medical device component manufacturer that is focused on producing molded parts for a particular industry.

The beginning expenses of molding die and equipment are rather expensive. Because of that, many people hesitate to start an injection molding business due to a lack of needed budget. Mold making is also another expensive task associated with injection molding. However, softer die substance is affordable but can not be used for large-scale production.

Our digital factories create prototypes and low-volume parts fast, while our manufacturing network, offers advanced capabilities and volume pricing.

The market for injection molding products is on the rise, and the demand for injection molded parts is thriving rapidly. There are many industries where injection molded parts are being used, such as the medical industry, automotive industry, consumer electronics, pharmaceutical industry, telecommunication industry, food and beverage industry, construction industry, packaging industry, etc.

The lead time of the injection molding procedure is relatively higher in comparison to other procedures. From product development, part design, material selection, mold tooling, sampling, and finally, manufacturing the products, the entire process will take several months. Due to the relatively long lead time, some people do not prefer injection molding businesses.

Starting an injection molding business can seem challenging if one does not know where to begin or what things are needed. To make it easy for people to get into the injection molding business, here we have listed the common steps involved in beginning the injection molding business.

Still another way to reduce molding costs, depending on your part volumes, is to consider on-demand manufacturing. At Protolabs, two injection molding service options are available (see table below). One is best suited for those who need smaller part quantities, usually associated with prototyping. The other option, Protolabs calls it on-demand manufacturing, is a good fit for those who require slightly larger part quantities, typically up to 10,000-plus parts from aluminum molds. On-demand production can be a great option to manage demand volatility of your parts, reduce total cost of ownership, and leverage cost-efficient bridge tooling.

Everyone wants to save money on manufactured parts. It sounds simple, but one of the easiest ways to reduce price-per-piece cost in injection molding is by increasing part quantity. That is because the initial upfront cost to design and machine the mold amortizes over more parts. At Protolabs, for example, up to 25,000 parts or more can be molded from the same tool.

SeaskyMedical uses reliable medical-grade raw materials to produce parts and inspect manufactured products. At SeaskyMedical, large orders are processed quickly for a lower price. Make sure to contact SeaskyMedical to get small-scale or large-scale injection molded products. They provide injection molding service to both domestic and worldwide clients, can be your reliable molding partners.

Every quote for an injection-molded part at Protolabs is accompanied by a free design for manufacturability (DFM) analysis. This identifies potential problem areas, or opportunities for design improvement. Insufficient draft angles, “un-machinable” features, impossible geometries—these are just a few examples in which part designs can and should be improved before clicking the “accept” button. Be sure to review these suggestions thoroughly, and contact an applications engineer at Protolabs with any design-related questions.

There is evident growth in the global injection molding market that is linked to the growing demand for high-quality injection molded products. Acquiring the injection molded components from a reliable plastic injection molding manufacturer is highly beneficial due to the low cost and quick production.

The mold tooling is a crucial part of ensuring that your molding company delivers precise, high-quality parts to the clients. It is highly recommended to hire mold design and tooling experts to handle the mold tooling requirements for your business.

The manufacturing plant layout is vital to successfully start your molding business. The production factory should have enough space to fit all the injection molding equipment and a clean room injection molding facility as well. Make sure to design separate spaces for testing the molded products and storing the manufactured products.

In addition to per-unit costs, consider the material. Many plastics overlap in strength and functionality, but some are inherently easier to mold, driving down part costs. You can experiment with different materials in the interactive quote you receive when you upload your design to Protolabs.

The injection molding business is profitable because it has the capability to produce large quantities of products within a short time. In addition to that, complicated designs can be produced easily via injection molding due to the mold design and tooling. Another benefit is that the plastic molding company produces little to no waste, and the leftover plastic can be recycled.

The injection molding procedure is compatible with various raw materials. The businesses can maintain stock of various substances, which makes it easier for material selection. There are many affordable and expensive raw materials as well.

The mold designers and tooling experts with enough experience can make the proper molds for your business. Therefore, it can become a little difficult to discover the right experts. In addition to that, hiring those skilled mold and tooling designers means one has to spend more money.

The injection molding procedure is only highly profitable in case of large-volume production. If the clients have ordered injection molding parts in small quantities, the molding business might not get much profit. This is because the mold design and tooling take up much of the budget.

When compared to various manufacturing methods, injection molding is known best due to its consistency. Due to the high-quality mold tooling, it is possible for businesses to produce exact parts for thousands of production cycles. Regardless of the design complexity, the business will be able to maintain the injection molded product consistency.

Our helpful design aid demonstrates part features that are too thin or too thick, bad bosses, right and wrong ribs, and other considerations to be mindful of while designing parts for injection molding.

It is to be noted that there are different types of injection molding methods, and choosing the proper method will ensure high profits. The most common injection molding methods are plastic injection molding, foam injection molding, liquid silicone injection molding, metal injection molding, and 3D printing. Depending on the type of products your business is planning to produce, it will be easy to pick the right injection molding method.

Finally, consider an overmolding option. Depending on the part, it might cost you more upfront, but could potentially save you money later. For example, overmolding a gasket on a part upfront might be an added cost, but it can save costs later from having someone install a gasket manually.

In addition, maybe you can join some of those parts with a living hinge? This method is a great way, for example, to mold two halves of a clamshell-style container. These parts would otherwise need a pin-type assembly to open and close. The only caveat here is that a flexible and tough material must be used, such as polypropylene (PP).

It is relatively easy to remove metal from an existing metal mold. Adding metal, on the other hand, can be difficult or, for all practical purposes, impossible with rapid injection molding. To look at this from the part perspective, you can add plastic, but you can’t take it away. Designing with this in mind is called “metal safe.”

While injection molding may seem costly compared to processes like CNC machining and 3D printing, the ability to scale and manufacture thousands of parts makes it a cost-effective solution for mass production. Determining the cost of injection molding is a combination of several factors. The main determinant of molding cost is the amount of time it takes to produce the tooling. This means, the more complex the part's geometry, the higher your manufacturing costs will be. Simple parts, without undercuts or more advanced surface finishes, will be the most affordable.

1. Eliminate undercuts 2. Get rid of unnecessary features 3. Use a core cavity approach 4. Reduce cosmetic finishes and appearances 5. Design self-mating parts 6. Modify and reuse molds 7. Pay attention to DFM analysis 8. Use a multi-cavity or family mold9. Choose on-demand production option10. Consider part size11. Use overmolding

Always consider part extents. In molding-speak, that means how big is the part, and will it fit comfortably in the mold while allowing for sprues, runners, ejector pins, and all the other considerations needed to make a mold work. Protolabs’ maximum part size for injection molding is currently 18.9 in. (480mm) by 29.6 in. (751mm) with a maximum depth from the parting line of 4 in. (101mm) deep. However, larger parts like these, in turn, require a larger mold. This may have an impact on your mold and part costs.

Got a family of parts that all fit together? How about multiple molding projects at one time? There’s no reason to build a mold for each individual part, provided A) everything is made of the same plastic, B) each part is roughly the same size (e.g., have similar processing times), and C) can all be squeezed into the same cavity, while still allowing for proper mold functioning.

Planning to sell injection molded products? In that case, finding a reliable plastic injection molding manufacturer is essential. SeaskyMedical is a China-based medical plastic injection molding producer with more than 10 years of industrial experience and Class 8 clean room. This company offers a one-stop molding service, including part design, material selection, mold tooling, and quick production and supply.

When the injection molding procedure has started, making alterations to the design will be difficult and expensive. It is because a new mold design and tooling are required, which will require more time and adds additional expenses.

However, maybe your molding project calls for only a handful of parts. No worries. Protolabs builds cost-effective molds for production quantities as low as 25 pieces, often within a few days of ordering.

There are various injection molding machines, and almost all of them have automatic functions. Due to these automated machines, human labor assistance is not much required. Because of the less human labor, custom plastic molding can save money on labor expenses.

Undercut features complicate and, in some cases, prevent part ejection. Get rid of them if you can, but maybe that’s not possible, if, for example, you need a side action, sliding shutoff or pick out. One alternative may be using sliding shutoffs and pass-through cores, or by changing the parting line and draft angles to provide an easier mold build. These reduce tooling costs as you avoid additional pieces to the mold that add to manufacturing costs. In addition to the rise in manufacturing costs of using hand-loaded inserts, this also may have an impact on your piece part price because of longer cycle times and manual mold operation.

There are many raw plastic materials that are compatible with the injection molding process, such as acrylonitrile butadiene styrene, silicone, polypropylene, etc. However, it is better to only source medical-grade raw materials from reliable companies that guarantee the credibility of the materials.

Some injection-molded parts go through multiple iterations until a final, workable design emerges. Instead of purchasing a new mold for every revision, a little clever planning will allow the same mold to be used multiple times. Starting with the smallest, most basic part design, mold as many pieces as needed, then re-machine the mold to include additional part features, or a larger, taller version of the same part, and mold again. This is not an exact science, but given the right part, this re-use approach can save dollars on tooling development.

Maybe you’re designing a snap-together case for some medical components, or two interlocking halves of a portable radio. Why build two mating parts when you can make one? Redesign the snaps so that the halves can be fit together from either direction, thus building a so-called “universal” part. Only one mold is needed, saving production expenses up front. And you can now mold twice as many of one part, instead of half the quantities of two.
