New Oven Decreases Energy Usage!
In January of 2023, K&H Precision Products purchased a new Grieve HC-1050 oven for the heat treatment of cast aluminum alloys. The new oven comes with the ability to design specific programs for required temper designations. Additionally, it allows us to run up to eight baskets through heat treatment operations at one time. The oven came with a Honeywell Truline DR45AT printer that monitors ramp time and temperature and gives the operator a printout at the end of the heat treat cycle. This allows K&H to monitor the process as close as possible to ensure that parts soak at their required solution temperature for the correct amount of time every night.
In addition to increased monitoring capabilities, the Grieve HC-1050 will also provide energy savings when compared to the previous oven. When calculated with the current electricity rate per kWh provided in our energy bill and assuming the same size load being used in both ovens, the HC-1050 will save approximately $16.50 per heat treat cycle. If K&H heat treats parts 5 days a week, 52 weeks per year, this adds up to over $4,290 in annual energy cost savings.

What Is the Plaster Mold Casting Process?
How Can This Foundry Service Benefit Your Prototype to Low-Volume Custom Parts Production?
Plaster mold casting services are one of K&H Precision’s numerous foundry capabilities. We provide innovative plaster mold-casting experience in a range of industries with leading expertise in custom prototyping applications.
When contrasted with many other conventional casting services, our plaster casting solutions offer closer-tolerance consistency, smooth finishes similar to die casting, as well as thin wall casting (TWC) capabilities (as low as 0.080”).
How the Plaster Mold Process Works
What Is Plaster Mold Casting?
Put simply, the plaster mold process is a gravity-fed casting method for thin-walled, detailed castings. This production process relies on a combination of metal casting plaster and hot water. The materials are carefully mixed to form a clean and highly detailed finished casting that exhibits precision tolerances and superior surfacing.
Plaster Casting vs. Sand Casting
Plaster mold casting provides closer tolerances and minimal wall thicknesses combined with smooth and consistent surface finishes for your custom-molded parts. This process is ideal for more intricate or thin-walled castings where a sand casting will have rougher surface finishes and require a minimum wall thickness of .187”.
The Benefits and Advantages of Plaster Mold Casting Services
K&H Precision’s plaster casting services provide a range of benefits when compared to other conventional casting methods, especially for your custom prototypes and specialized low-volume parts manufacturing.
- Consistent close-tolerance custom molded parts. For a full rundown of our plaster mold dimensional tolerances, refer to the chart below.
- Ability to cast wall thicknesses as thin as .080″.
- Yields greater definition of detail.
- Leaves a smooth surface finish similar to die casting 90 – 120 micro inch finish.
- Lower initial investment to get your product to market and/or for assembly and design testing purposes.
- Ideal prototype process prior to your transition to die casting.

Can These No-Bake Foundry Services Benefit Your Prototyping / Low-Volume Manufacturing Application?
Sand casting services (sometimes referred to as sand-mold casting) are some of the many no-bake foundry solutions we specialize in at K&H Precision. Compared to the popular green-sand casting process, our specialized no-bake casting capabilities provide closer tolerances, premium surface finishes, and in-house core making for quicker lead times and complete process control.
What Is No-Bake Sand Casting?
The no-bake sand casting process relies upon specialized chemical binders to create reliable, high-strength molds. The sand is fed into the mixer via gravity, while the chemicals are blown into the mixer via air. The process does not require baking, which is where the term ‘no-bake’ comes from, and another common term is ‘air set sand casting’. The casting can be built around more complex, close-tolerance geometries while providing a low-cost prototype to low-volume production casting comparable to the quality of a permanent mold casting. This makes the process especially suitable for large-format commercial and industrial castings that require advanced design features.
A Brief History of the Sand Casting Process
Sand casting is one of the world’s oldest methods of metal forming. Its roots stretch back over 3,000 years, with ancient Chinese civilizations using clay molds to cast bronze statues, tools and other metal products.
Throughout the centuries, the commercial manufacturing sector has thoroughly refined the sand casting process. New materials and methods have been constantly engineered to produce more consistent molds that allow for the manufacturing of higher-quality, lower-cost products. No-bake sand casting is just one of the industry’s many exciting technological advancements that K&H Precision Products is proud to be a part of.
No-Bake Sand Casting vs. Conventional Sand Mold Casting
No-bake sand casting processes can be utilized to produce molds with exceptional dimensional tolerances and complexity. If your custom-molded components require the utmost in precision tolerances and consistency, our no-bake casting services are the answer. As an additional benefit, the finished casting surface is much smoother and more consistent, allowing for the manufacturing of more premium products with improved aesthetic designs.
The no-bake process is also one of the industry’s most economical and efficient casting techniques, both in price and in quality. A final standout feature of this streamlined manufacturing solution is that the casting is produced without combustion (and its subsequent byproducts). As a result, K&H can produce precision castings that are aesthetically pleasing while still having low levels of porosity and shrink.
The Advantages of K&H Precision’s No-Bake Sand Casting Services
Close-Tolerance Consistency: Tighter design tolerances: refer to the chart below for an expected tolerance range.
Precision Thin-Walled Pattern Making: Our no-bake casting process enables us to produce a complete range of wall thicknesses from .187″ and up.
Premium Surface Finishes: A better, more consistent surface finish compared to conventional sand casting solutions. We can achieve 200-500 micro-inch finishes to provide your custom-molded parts with a superior aesthetic. Surface finish can be assumed with draft in mind; the more draft allowed, the smoother surface you will have.
Complex Custom Designs: We can create custom patterns with far more complex geometry than can be achieved through traditional oil-bonded sand castings. In-house core making gives us complete control of your project, lowering lead times and ensuring quality and customer service every step of the way.
