So You Need Custom Injection Molded Parts Yesterday…

In our last blog we focused on speed-to-market solutions in prototypes and production machining. We also referenced a Quick Manufacturing Solutions (QMS) process for “managing the queue”, as a means of saving time and resources from design through production and part delivery.

This “one-stop” approach to development of precision molds and tools and production injection molding is highly valued. Our QMS process does not stop at model making and rapid prototyping. We help “manage the queue” with value-added materials selection and sourcing, design for manufacturing, secondary operations, and logistics support services. With a focus on customer solutions Harbec is always looking to improve our equipment, capabilities, and ability to provide tightly tolerance precision parts with 100% on-time delivery.

If you require mold making and production our proprietary QMS methods will provide rapid tooling which also reduces the time for mold making and the cycle time in production. This will save valuable time resulting in a reduction in total life-cycle manufacturing costs for the part. The QMS process enables our customers to be more agile and achieve their speed-to-market objectives.

A flexible approach to mold making leads master toolmakers to be experts in the use of cutting edge process equipment as they continually develop their craftsmanship and know-how to construct conventional steel molds or aluminum bridge tools. This deep cross-functional expertise required of toolmakers plus flexibility in design, equipment capabilities, materials, and skills allows for the best value molds and tools in the quickest amount of time.

Focusing on improving time to market needs and having awareness that most product life cycles are becoming shorter and shorter is critical.  To address both of these trends Harbec has developed what we call “hybrid” tooling solutions.  The hybrid solution balances strong structural steel with easily machined, very thermally conductive and extremely strong aluminum alloys designed specifically for production injection molds.  This combination gives an advantage on lead-time while also offering a tremendous advantage for reducing costs for the mold and parts due to improved cycle times.  Harbec has been working with a variety of aluminum alloys for more than 15 years and we are experts at providing affordable solutions, within a very short lead-time, combined with outstanding quality.

Approximately 60% of our production molds are made from aluminum. Aluminum has been a choice for many customers as it offers benefits for reducing the time to contrast the mold to the cycle time within the injection molding machine (aluminum has superior thermal conductivity which give us 25-40% faster molding cycles). In fact, aluminum molds can be achieved, on average, for half the machining costs of steel molds. Further, aluminum molds can be completed in two to four weeks instead of 10-14 weeks which is customary with steel. Additionally, the tolerances and molding quality of the same plastics are equal with aluminum as with steel. 

Advantages of Aluminum

Material Cost Lead Time Rated Cycles
QC10Aluminum Lowest 2–5 weeks 25,000 – +100,000¹
P20Tool Steel Midpoint 6–8 weeks +500,000
H13Tool Steel Highest 8–13 weeks +1,000,000

¹Rated Cycles – determined by:  part geometry; texturing; shut-offs; draft; material abrasiveness.

The art of planning and proactive project management are essential to success. Integrated teams provide customers with the best talent and know-how for their challenges.  To achieve short lead times Harbec uses only six mold-block sizes which can accommodate most any mold design and configuration our diversity of customers have required over the years. Those blocks are pre-machined and stored them for quick access. Having an inventory of materials like this can save critical minutes, hours, and days during a project. It is this kind of thinking and pre-planning that earns new business, and trusted partnerships in the manufacture of precision tools and molds and custom injection molded parts.

We frequently receive quotes for conventional and bridge tooling with very short lead times. Harbec understands the speed of business is dynamic and requires partners that can provide fast turn-around not just on quotes, but also on finished product.
