Product Features

The 9oz square spice jar with cap is manufactured using a precision injection molding process. The mold has undergone multiple rounds of structural optimization during long-term mass production, ensuring consistent performance regarding corner transitions, wall thickness distribution, and overall verticality. The 250ml square design prioritizes packing density and storage stacking efficiency; consequently, specific parameters control the flatness of the outer walls and corner shrinkage during molding to minimize dimensional variations between batches.
Food-contact grade plastic resin is used as the raw material; flow uniformity is maintained via stable injection profiling during the high-temperature melt phase, while segmented temperature control during cooling minimizes the risk of warping. The jar mouth and cap feature a matched tolerance design, with consistency across production batches verified through sampling-based torque and seal integrity testing during assembly.

Sampling Policy
For the 9oz square spice jar with cap Wholesales, the mold's runner system and cooling parameters undergo minor adjustments during the sample development phase to ensure that the initial trial molding yields an appearance and structural integrity close to mass-production standards. To meet specific client requirements, we verify dimensions, neck-to-cap fit precision, and cap threading smoothness during the prototyping process; we also simulate actual production pacing through small-batch trial runs to minimize structural deviations in the subsequent mass-production stage.
Standard samples can generally be arranged within 3–7 days using existing molds and standard processes; however, if adjustments to color, logos, or surface finishes are required, the production timeline is re-evaluated based on the complexity of the specific processes. Once the design is finalized, custom samples enter a dedicated production workflow, with technical staff overseeing first-article inspection and process monitoring to ensure consistency between the sample and the final mass-produced product. Sample costs can typically be offset against future formal orders, with specific terms determined based on order volume and the nature of the partnership.

Delivery Schedule Information
For the 9oz Square Spice Jar Supplies, production scheduling is typically determined by existing mold inventory and current injection molding machine workloads. Standard, non-customized orders-assuming sufficient raw materials and no requirement for secondary processing-can generally be completed (including production, inspection, and packaging/shipping) within 7–15 days.
Orders involving customization-such as color adjustments, logo application, or packaging changes-require additional process transitions and technical validations across injection molding, post-processing, and packaging lines; consequently, the overall lead time typically ranges from 15 to 30 days, depending on process complexity and the speed of approvals. Large-volume orders are coordinated based on the factory's master schedule, machine cycle times, and raw material procurement timelines to ensure consistent production cadence and quality stability; final delivery dates are confirmed based on order volume and available production windows.
FAQ
Q: How long does sample preparation take?
A: Standard samples typically require 3–7 days. Customized samples may require additional time depending on artwork, color matching, or packaging requirements.
Q:What is the lead time for bulk production?
A: Standard orders generally require 7–15 days. Customized orders typically require 15–30 days after sample approval and order confirmation.
Q:How do you ensure product quality?
A: Quality control procedures include raw material inspection, production monitoring, dimensional verification, assembly checks, and final inspection before shipment.
Q:Can you handle long-term supply programs?
A: Yes. For customers with recurring demand, we can arrange production planning, inventory coordination, and scheduled shipments to support long-term purchasing programs.
