Moldmaking can be a difficult business to accurately forecast. Work comes in when the OEM/brand owner is ready, and the ability to impact the project launch is out of the hands of the tool shop. The lure of growing a tooling business by expanding into custom production molding is one that has attracted and continues to attract many tool-shop owners. Having a revenue stream built on the production of a planned number of components certainly sounds like a much easier way of making a living. However, competing and performing successfully as a production molder requires a great deal more than simply purchasing injection molding machines, then putting pellets in one end and counting the money that comes out the other.
Certainly, one of the largest expenses is the equipment and expanded facilities required for the job. All modern tool shops understand the cost of high-performance machining technologies. On the shop floor, high speed, high precision and high repeatability all come with a high price tag.
The cost of the equipment required for production molding is not necessarily a barrier to entry, as most tool-shop owners generally make five- and six-figure investments for machine tool technologies. A very significant challenge is the cost and time needed to attract and develop a new set of talent. Just like on the tool-shop floor, where experienced and skilled journeymen are critical to success, the molding floor requires engineering disciplines, including process engineers, quality system administrators, mold setup technicians, material handlers, press operators and equipment maintenance personnel.
In addition, production molding also requires a significant investment in facility space—room for molding, assembly and value-added operations; space to store and dry the resins; warehouse real estate to store the product prior to shipment; and so on. That leaves the tool shop with two choices: either buy an existing molding operation or develop one on its own.
Oftentimes, the tool shop looking to grow into custom molding is one that is likely already dealing with a mix of customers—certainly the OEM/brand owner—and that appears to make the decision a logical one. For the shop whose long-time customer base is primarily comprised of custom molders, there very well may be (and perhaps should be) a reluctance to compete directly with the source of its core business revenues.
The plastics business landscape was a different animal 30 years ago. For the most part, OEMs (those without internal injection molding capabilities) regularly worked through their sources of part supply, leaving the decision of tooling strategy
to the chosen custom molders. The tool shop did not have direct contact with the OEM, and the tooling concept was primarily driven by what best suited the existing capacities and technical capabilities of the molder.
This was certainly not always a negative, however it did preclude the OEM from being exposed to and considering alternative tooling and molding concepts. By the early ‘90s, many OEMs were going direct to the tooling source, driving a focus on production through upfront engineering. This was especially true of companies whose product line’s success was based heavily on speed to market, such as telecommunication devices, computer accessories and storage, and other retail-based consumer items.
In the automotive industry, plastic injection plays a fundamental role in the manufacturing of parts and components that must meet high standards of precision, durability, and lightness. The design and manufacturing of injection molds have undergone a series of innovations that optimize production times, reduce costs, and improve operational efficiency. In this article, we explore the main trends driving the development of injection molds in the automotive sector.

Our expertise has allowed us to work closely with automotive component manufacturers, offering cutting-edge solutions that meet specific needs for precision, durability, and efficiency. In this article, we explore the emerging trends in the design and manufacturing of injection molds that are transforming the automotive industry.
Optimization of Cycle Times
One of the key challenges in automotive manufacturing is the mass production of parts on a large scale without compromising quality. The latest technologies in mold design focus on reducing cycle times, allowing more parts to be produced in less time. Some solutions include the use of conformal cooling systems, which optimize heat transfer within the mold, speeding up the solidification process of molded parts.
Advanced cooling systems, custom-designed for each mold, allow precise control of the temperature in critical areas of the mold. This not only reduces cycle times but also improves surface quality and part consistency, reducing the rejection rate and improving production efficiency.
Increased Focus on Sustainability
Sustainability is becoming increasingly prioritized in the automotive industry, and injection molds are no exception. The use of recycled plastics and biopolymers has gained ground, and mold manufacturers are adapting their designs to ensure these materials, which can be more difficult to process, are injected with the same efficiency as traditional plastics.
Additionally, advances in gas and water-assisted injection technology allow for the production of lighter parts, reducing the use of plastic materials without compromising the stiffness or mechanical properties of automotive components. This trend is directly related to the industry’s efforts to reduce vehicle weight and, consequently, improve energy efficiency.
Integration of Smart Molds
The development of smart molds is another major trend revolutionizing automotive production. Thanks to the incorporation of real-time sensors, molds can now monitor critical variables such as injection pressure, mold temperature, and cycle times, allowing for automatic adjustments during production.
This continuous monitoring and dynamic adjustment capability results in greater precision of parts and improved final quality. Additionally, it facilitates predictive maintenance, reducing unplanned downtime and extending the mold’s lifespan.
Innovations in Mold Materials
The use of advanced alloys and high-durability materials in mold manufacturing is also on the rise. These materials enable molds to better withstand the intensive working conditions of the automotive industry, where parts must be produced in large volumes without compromising mold integrity.
Materials such as hardened stainless steel and other alloys offer better wear resistance, extending maintenance intervals and increasing mold lifespan, which in turn reduces production costs.
Additive Manufacturing for Rapid Prototyping
Additive manufacturing or 3D printing is being integrated into mold development, particularly in the prototyping phase. This allows mold manufacturers to test more complex designs and make quick modifications without incurring the costs and time associated with traditional mold production.
Additionally, some mold components, such as cooling channels or inserts, can be manufactured using additive technologies to improve the mold’s thermal performance and reduce cycle times. This flexibility in design and production allows molds to be customized according to the client’s specific needs and the characteristics of the part to be injected.

Trends in Mold Manufacturing in China
Adoption of Advanced Technology
In the past, operators in the Chinese mold industry were limited by lower technology adoption rates compared to Western countries. However, the combination of CNC machining, 3D printing, and AI-powered automation gaining traction has helped enhance the productivity, accuracy, and lead times of factories in China, which helps them remain competitive in the global economy.
Emphasis on High-Quality Production
For a long time, Chinese mold makers had a reputation for being cheap but not very high quality. This is quickly changing, though, as an increasing number of providers invest in R&D and align with international standards such as ISO 9001. This not only makes their products more durable but also improves their overall performance.
Increased Need for Tailored Solutions
Industries require specific custom molds at an individual level. Whether it’s injection molding of plastic parts or die casting of metal components, Chinese mold factories provide custom-made solutions for specific design and functional requirements.
Sustainable and Green Practices
Sustainability regulations in China are getting stricter and more advanced. This compels mold factories to meet environmentally friendly standards. In an effort to comply with ecologically sustainable norms, companies are putting energy-efficient machines into use, recyclable materials are being introduced, and industrial wastes are being minimized.
Growth of International Trade
China’s mold industry is one of the leading exporters to the USA, Europe, and South-Eastern Asia. The new surplus in their competitive pricing, together with an increase in quality, has led most international companies to blindly prefer a mold factory in china rather than local producers.
