Whether you need consistent surface quality, efficient cycle times, or long-term production reliability, this mold is built to elevate your product line.
Our mold is the result of years of precision tooling experience and strict quality control. The S136 mold steel offers superior corrosion resistance, excellent polishability, and high wear resistance – ideal for producing thousands of shiny cosmetic compacts without surface degradation. The 1×4 cavity design balances productivity and part quality, making it suitable for medium-to-high volume production runs.

Choosing the right mold directly impacts your product’s market appeal. Our cosmetic compact mold delivers consistent gloss across every cavity, reducing rejects and rework. The S136 steel ensures the mold withstands the chemical corrosion from pigments and fragrances often found in cosmetic formulations. With a 1×4 cavity arrangement, you gain an ideal balance between production speed and per-part quality – perfect for launching new compact designs or scaling existing lines.
Beyond technical specs, we offer full support from design review to trial runs. Our engineers can suggest modifications to the cooling circuit or gate location to optimize your specific resin and part geometry. We also provide detailed mold maintenance guidelines to extend the mold’s service life.

Frequently Asked Questions (FAQ)
Q1: What is the typical lead time for this 1×4 cavity cosmetic compact mold?
A: Standard lead time is 25–35 working days after design confirmation and down payment. Rush orders can be negotiated.
Q2: Can the cavity number be changed to 1×2 or 1×8?
A: Yes, we can customize the cavity layout to match your production volume. Please provide your target annual output, and we will recommend the optimal number of cavities.
Q3: What materials are suitable for this mold? I need to mold polycarbonate (PC).
A: The S136 steel with mirror finish is compatible with most thermoplastics, including PC. However, PC may require higher mold temperature and special gate design – we can adjust the cooling and gating accordingly.
Q4: How do you ensure the mirror finish is consistent across all four cavities?
A: We use CNC machining with fine finishing passes, followed by manual diamond polishing and final lapping. Each cavity is measured with a profilometer; the roughness is guaranteed to be Ra ≤ 0.02 μm. A trial mold is run to visually confirm the gloss.
Q5: Do you provide samples before mass production?
A: Yes, after the mold is finished, we will run a T0 sampling and ship you the molded samples for approval. Minor adjustments can be made before final acceptance.
Q6: What certifications does your factory hold?
A: We are certified under TS16969 (automotive quality management system, also applicable to high-precision molds). Additional certifications like ISO 9001 can be provided if required, but currently TS16969 is our primary standard.
Q7: Can you provide a warranty for this mold?
A: Absolutely. We offer a standard 12-month warranty covering manufacturing defects. Extended warranty plans are available upon request.
Q8: How is the mold packaged for international shipping?
A: The mold is cleaned, rust-proofed, and secured in a sturdy wooden crate with cushioning. We also include a detailed maintenance manual and spare parts (e.g., O-rings, springs). Shipping is via sea or air, FOB from Jiangsu, Shanghai, or Shenzhen.
