Is mold testing worth it?

Mold is a serious problem, and spotting mold contamination before it grows out of control can save you thousands of dollars. This makes the cost of a mold inspection well worth a few hundred dollars when you are buying a new house. Mold testing, however, is not really worthwhile.

Which is better TPU or TPE?

TPU is more abrasion resistant than TPE. This property makes TPU last longer in working parts. TPU retains its elastic properties in colder temperatures. TPU naturally has a higher resistance to chemicals, such as oils, greases, and a variety of solvents.

Will 3D printing replace CNC?

3D printers do not have the precision needed for mission-critical uses. Even when engineers use Selective Laser Melting technology for printing 3D parts in metal, its accuracy can't match that of CNC machines. For example, 5 axis CNC milling can create mechanical accuracy of 1 micrometer on each of the axis.

Can you pour silicone into a silicone mold?

Can I add additional uncured silicone rubber to a silicone mould that is already cured? As long as the surface of the cured rubber is kept dust and grease free, more silicone rubber of the same type can be poured on top and will bond with the surface.

Does silicone leach into food?

Many experts and authorities consider silicone completely safe for food use. For example Health Canada states: "There are no known health hazards associated with use of silicone cookware. Silicone rubber does not react with food or beverages, or produce any hazardous fumes."

Why is silicone bad for the environment?

Silicone isn't the most environmentally friendly material on the market. Producing silicone uses hydrocarbons derived from petroleum, which isn't sustainable. It's difficult to recycle, and most facilities won't accept it. With that said, silicone is a suitable alternative to plastic — it's just not the best.

Why did my resin stick to my silicone mold?

Your silicone mold isn't fully cured.

If your mold has spots of uncured silicone, the resin will stick in those places and tear when demolding. This most commonly happens with tin cure silicone molds.

Is there a future in 3D printing?

1. 3D printing will be bigger, faster and cheaper. 3D printing technologies are developing quickly. Rising demand for specialized materials to fulfil the required properties of end parts will continue to drive developments in the range and types of options available.

How much does it cost to get a mold made?

Simple molds are typically in the $3,000 and $6,000 range while the price for large, more complex, high-production, or multi-cavity molds can cost $25,000 to $50,000 or more. Considering all the variables involved will help determine the overall injection mold cost.

Can I put silicone candy molds in microwave?
