Import Alm Lsr Baby Straw Nipple Mould — Buy in wholesale FOB from Supplier in China

This liquid silicone rubber mould is purpose-built for manufacturing baby straw nipples, featuring a 6 or 8 cavity layout tailored to medium-volume LSR production. The core is fabricated from S136 stainless tool steel, heat-treated to HRC 48-52, paired with a #50 steel mould base that can be substituted per buyer specification. A cold runner architecture conserves raw silicone by keeping runner channels below cure temperature, while the mould operates within a 90 to 180 degrees C temperature band during injection. The projected service life reaches 1,000,000 shots, and the supplier quotes 35 working days for delivery following order confirmation. Compatibility is confirmed with 130T and 150T LSR injection presses equipped with 1:1 A/B component dynamic and static mixing.

The straw nipple geometry introduces undercut challenges absent in simpler spoon or pacifier forms, demanding precise core and cavity alignment to maintain consistent wall thickness and avoid flash at parting lines. S136 steel's corrosion resistance proves essential given the acidic nature of platinum-cure LSR by-products and potential sulphurous additives in medical-grade formulations. The HRC 48-52 hardnessrijn provides adequate compressive strength for the small-diameter straw bore cores that are prone to deflection under injection pressure. Cold runner selection for this nipple application follows industry convention, though the slender straw channel may require venting considerations not explicitly detailed in the source data. Standard practice for baby nipple moulds mandates mirror-polished surfaces below Ra 0.03 microns to satisfy food-contact regulations and facilitate demoulding of the elastic LSR article.

Buyers are typically baby bottle OEMs, LSR converters serving the infant feeding market, or brand owners developing private-label straw cup systems. The mould's 6 or 8 cavity options allow production scaling without committing to the higher investment of 16-cavity tooling. Packaging for export generally involves anti-corrosion film, desiccant, and plywood crating, though buyers must confirm specifics. Lead time of 35 working days assumes prompt drawing approval and material availability; no buffer for revision cycles is stated. Payment structures, spare parts inclusion, and after-sales support require direct negotiation with the supplier, as the available data does not address these commercial terms.

Guangzhou Alm Plastic & Silicone Mould Products Co., Ltd. operates from C6, No.32, Nanpu Village, Shilian Road, Shiji Town, Panyu District, Guangzhou, Guangdong, 511450, China. The company carries a 'harbor' trust tier with zero recorded response activity on this platform, both in rate and average hours. No information is provided regarding year of establishment, registered capital, employee headcount, factory area, annual revenue, or named clientele. The address situates the firm within a known Guangzhou plastics manufacturing corridor, but geographical proximity to industrial peers does not confirm equivalent technical capability or financial stability.

The supplier's product orientation centres on OEM LSR mould fabrication for baby feeding articles, with this listing focused specifically on straw nipple tooling. The profile lacks disclosure of quality management certifications (such as ISO 9001), design software platforms, CNC machining capabilities, or in-house mould trial facilities. No export license numbers, intellectual property registrations, or trade show participations are listed. Buyers considering a tooling investment should independently verify factory existence through business registration checks, request facility tour documentation, and seek customer references outside platform-mediated channels. The absence of response data suggests reliance on direct communication rather than platform inquiry systems.
