In-House Bottle Molding

Jarsking assist clients to bring an idea/concept to reality. Right from the beginning our design team aims to ensure that the technical quality of the bottle, as well as the aesthetic requirement is of high standard.

Good Production Starts with Professional Mold Design

Our product development consultants have an average of 10+ years of experience in developing custom glass molds. We understand evolving retail and consumer dynamics and know how to balance form and function, creating eye-catching packaging that addresses the operational realities of production.

Custom Bottle Molding

Every custom mold presents a challenge: it must meet a creative team’s standards for art and aesthetics while also adhering to the science and engineering required for successful blow molding.

The right partnership is key for a successful outcome and a final product that meets everyone’s standards for appearance, performance, cost and availability.

Right Start with Details

At Jarsking, our custom mold development process begins by working with a brand’s creative team to learn more about their vision for their custom bottle.

We ask questions that help guide us in the manufacturing process: What is the bottle going to look like? What will it contain? Should it be rigid or squeezable? How will the bottle be decorated? Each of these questions leads our team down a path to identifying the right processes, materials and other aspects of your custom mold project.

Getting the right questions answered upfront can mean the difference between having a prototype approved in weeks or going back to the drawing board to address issues that weren’t identified in the early stages of design.


Thoughtful Molding Solutions

After our team has defined these parameters for the molding process, we can move into manufacturing considerations.

For PET bottles, we often start with our existing library of preforms, to evaluate whether or not an existing preform can be used to blow the bottle. If we can use an existing preform, we can save the brand owner mold costs and significantly shorten the development process.

With hundreds of preforms in our company, we often has an existing preform from which to make a custom bottle or jar. If an appropriate preform does not exist – for example, if the you need a special neck on the bottle, or a heavier or lighter bottle than normal – we work closely with you to create a custom preform that is optimized for your new bottle.
