Product Design

Integrated Sprayer & Pump Manufacturing
Custom automated assembly machines for trigger sprayers, lotion pumps, mist sprayers, foam pumps and daily chemical packaging components.
Core Solutions











Actual molded components can be tested directly on the assembly system before shipment.
Our mold and automation teams work together to identify component, tolerance and assembly issues.
Before shipment, the machine undergoes testing that simulates the customer's factory environment; once it passes the test, it is ready for immediate use.

Key points for engineering, production and procurement teams.
Yes. One project can cover part review, mold development, trial molding, automatic assembly, inspection and production acceptance. The final scope is based on your samples, drawings and output target.
Yes. We can review your existing production assets and identify whether the project needs new tooling, automation, component improvement or selected station upgrades.
Product samples or drawings, resin, assembly sequence, target output, quality checks, available floor space and electrical standards are helpful. Our engineers can help complete missing details.
Approved molded parts are checked for critical dimensions and functional behavior, then used for feeding, assembly and inspection testing under agreed production conditions.
Yes. Project support can include installation guidance, commissioning, operator training, documentation, spare-parts planning and ongoing troubleshooting.
The standard production cycle is about 3 months from technical sign-off, with exact timing depending on project complexity, validation requirements and the confirmed factory schedule.
We run custom tooling on in-house injection molding machines, transfer freshly molded components to the automated assembly line, and verify machine-part matching, key functions and agreed acceptance targets before shipment.
Yes. Songrock can review technical feasibility, product structure, resin options, mold layout, assembly sequence and output targets, then recommend a practical route from concept development to stable production.
