Clean and prepare molds, including applying mold-release products. Accurately measure polyurethane components and pigment using scales and specified mixing ratios. Mix and pour materials within the required working time. Secure molds and monitor cure and demolding times. Demold parts carefully to protect the product and tooling. Trim excess material and finish parts to the demonstrated standard. Fill small, repairable voids using the provided repair material. Identify and set aside parts with major voids or other unacceptable defects. Inspect finished parts to confirm they meet the shipping-ready standard. Maintain production records and leave tools, molds, and the work area clean and organized. Follow established procedures and use required protective equipment. Experience and Qualifications We are looking for someone comfortable with: Two-part polyurethane foam or closely related molding and casting materials. Mold preparation, mold-release application, and demolding. Measuring, mixing, adding pigments, pouring, and monitoring cure times. Trimming, finishing, and minor surface repairs. Appropriate hand and power tools. Safe chemical handling and required PPE, including gloves, eye protection, and respirators where required. Reliability, attention to detail, consistent quality, and the ability to work independently after training are essential. Training and Equipment Hands-on training will be provided for this specific part, tooling, and production process. You will work alongside the current operator to learn the process, make parts together, and establish readiness to work independently. A finished sample and acceptance criteria will be reviewed during training so you understand what qualifies as a completed, shipping-ready part. All necessary materials and tools are available on-site. Required PPE will be provided. If you have personal PPE or tools you would like to use, you are welcome to bring them for review and approval before use. Piece-Rate Compensation The piece rate is $15 for each completed part that meets the demonstrated quality standard and is ready to ship, including required trimming, finishing, and any minor repairs. Parts with major defects that cannot meet the acceptance standard do not qualify for the completed-part piece payment. Required compensation for training, other work time, and applicable wage protections will also be provided.

Earnings example:

Three completed, shipping-ready parts in one hour generates $45 in piece-rate earnings. This pace has been achieved by the current operator after approximately two months working with the process. Actual output varies; this example is not a guaranteed hourly rate. Payment is made weekly by check on Fridays. Morning-shift workers receive payment by the end of the workday; evening-shift workers receive payment when arriving for their Friday shift.
