King Rubber retains ownership of the referenced tool.

What specifications does King Rubber require on the application to receive an accurate quotation on the product?
Please provide the estimated annual-usage, material specifications and drawings or descriptions of the rubber parts.
Why does Tooling and Sample Delivery take 4-6 weeks?
The Tooling and Sample Delivery process will take 4-6 weeks, as the customized tool must be produced first. Then during tool production, we may have to design a new tool or adjust the existing tool to reach the exact specification. Once the tool is completed, we will manufacture a sample and send to you for approval, along with product documentation.
Is King Rubber ISO-certified?
Our company’s ISO-certification has been in effect since 1998. King Rubber is an ISO 9001:2015 certified company.
Can you do rubber-metal bonding?
Our company currently offers customized rubber-metal bonded parts from smaller to larger sizes, ranging from less than 1-inch in diameter – to over 1-foot in total length.
Can you use our existing tools in your equipment?
Yes, in some cases, our company can use your existing tools based on several factors: including mold type, size and age. Please discuss with your King Rubber representative for the possibility.
Do you have any spare parts?
Since most of our custom rubber parts are made with the customer’s own tools, we do not normally act as an inventory company. However, we do have some parts that can be used more frequently and we may have stock such as plugs, buttonholes and some pipes. We can also store parts according to your needs, which we currently supply to many customers. We will ship the goods according to your schedule.
How long will it take for me to receive a quotation after my initial inquiry?
Our company will send you a quotation for plastic products in 5 – 7 business days. The quotation for extruded rubber or die-cut parts will be in 3 – 5 business days.
What is the lead time for samples and tools?
The delivery time for molds and samples is usually 4 to 6 weeks for extruded samples and 6 to 8 weeks for molds and samples.
What is the lead time for producing parts?
Production parts are based on sample approval. For extrusion/die-cutting production, the delivery cycle is about 4 to 5 weeks, and the molding parts production is about 5 to 6 weeks.
Do you do PPAP?
Yes, we do PPAP. This information should be communicated to King Rubber when submitting a request for a quote and any other relevant information (i.e., testing) related to the shape/fit/function of the part.
Do you use sponge rubber?
Yes, we use sponge rubber, extruded and molded.
Are you using plastic?
Yes, we manufacture and produce plastic products: extruded and molded.
Can you determine the appropriate polymer and hardness for my application?
Yes, our experienced team of experts can guide you to determine the right type of rubber or polymer, depending on the application and environment your parts will be exposed to.
Can you send my order directly to my customer?
Yes, in many cases.
Why do I have to “sign” these pre-production/sample parts before the production order runs? I will buy this order as soon as possible!
You can waive the right to sample approval, but in the process you also waive the subsequent right to change or correct the parts prior to actual production.

Extrusion unit – 40 hardness tester
Molded part – 30 hardness tester
