  2024年至今(截至2025年4月24日收盘),双林股份股票累计涨幅高达665%,区间最大涨幅超过14倍。截至4月24日收盘,双林股份市值为317亿元。

  双林股份是老牌汽车零部件龙头,其自2024年以来股价的突出表现,一部分与其业绩表现有关,2024年其归母净利润增幅超过5倍。另一方面则来自于市场对其人形机器人行星滚珠丝杠产品的高期待,这一产品目前已经对接行业头部人形机器人公司,预计将很快形成营收。

  股价上涨超5倍,净利润增长超5倍,双林股份究竟是怎么做到的?

  宁波父子,

  把小塑料厂“折腾”成汽配龙头

  2000年5月,一辆吉利美日两厢轿车从吉利北仑基地下线。这是宁波汽车工业史上首台乘用车整车,也开启了宁波汽车零部件企业的黄金时代。

  邬永林敏锐地察觉了汽车行业的机会,当年11月设立了宁波双林精密模具有限公司,正式进入汽车零部件企业。

  当时创业已经十余年的邬永林深知,机会稍纵即逝,及时抓住机会才能成功。

  1955年,邬永林出生于一个渔民家庭,家境贫寒,只上了四年小学就休学干活补贴家用,每天早上三四点钟骑着自行车到市里卖海鲜。

  1987年,已经32岁的邬永林拿着全部身家2000元,开了一家塑料制品厂,开始为当地洗衣机厂加工泡沫垫片,干的都是最简单的活儿。但很快,邬永林迎来了事业转折点。

  电子工业部组织全国联合设计出了彩电核心部件——高压回扫变压器塑料骨架,但没有一家企业敢承担开发模具的工作。邬永林当机立断,接下了这个任务。他迅速从上海、昆明聘请了5名高级模具技术人员,并从银行贷款,甚至借了一笔高利贷,开展研发。

  两年后,邬永林的厂子成功开发出模具,在市场上站稳了脚跟。凭借着这一产品的成功,短短几年间,邬永林的小塑料厂逐渐发展成集团企业,更名为双林集团。

  双林模具对汽车行业的接触,实际上开始于1998年,这一年公司开始争取上海联合电子的国产化订单,为其开发汽车小油桶的模具,联合电子也是双林在汽车领域的第一个客户。

  2004年,邬永林由于身体原因,把企业的管理权逐渐交给儿子邬建斌,双林模具的业务也从最开始的塑料件扩展至汽车内外饰、精密模具、新能源电机等核心部件。

  2010年,双林股份在创业板上市,成为宁波汽配产业第一家上市公司。

  在经营企业上,邬建斌比父亲更爱“折腾”,他将这种折腾视为一种探索。在接受媒体采访时,邬建斌曾表示,企业需要折腾,所谓折腾就是要累积经验。

  2014-2017年,双林股份先后进行了多项收购和投资:收购湖北新火炬进入汽车轮毂轴承市场;投资知豆汽车;收购德洋电子进入新能源电机、控制器市场;收购上海诚烨进入冲压件与焊接件市场;收购双林投资拿到澳洲DSI变速箱资产。

  这样的“折腾”迅速拓展了双林股份的业务边界,但也带来了较大损失。

  2018年,知豆汽车销量暴跌,陷入严重经营困境,双林股份所持的知豆汽车股份价值迅速缩水。与此同时,为知豆汽车提供电机部件的德洋电子也因为知豆汽车拖欠货款而出现资金危机。

  除此之外,双林股份其他收购的资产也出现了商誉减值的情况。这一年,双林股份实现归母净利润为-6182.02万元,这是其上市以来首次亏损。若扣除非经常性损益,其亏损高达5.03亿元。进入2019年,双林股份亏损幅度进一步扩大,归母净利润达到-9.47亿元,扣非净利润为-10.60亿元。

  2020年后,双林股份逐渐摆脱商誉危机。随着近年来新能源汽车市场的快速发展,其业绩也开始逐渐恢复。

  2024年,其营收高达49.10亿元,同比增长18.64%。归母净利润达到4.97亿元,同比大增514.49%,创出上市以来历史新高。扣非净利润为3.26亿元,同比增长317.74%,增速惊人。

  2025年一季度,双林股份营收增长20.97%至12.86亿元,归母净利润同比增长105.49%至1.59亿元,多家券商表示其业绩超出预期。

  随着业绩复苏以及新业务的拓展,双林股份股价在资本市场上表现十分亮眼。2024年至今,双林股份股价累计涨幅高达665%,最新市值高达317亿元。

  加码滚珠丝杠,押注人形机器人

  双林股份股价之所以在资本市场爆发,一方面与其业绩加速复苏有关,另一方面得益于新业务的开展。

  2024年,双林股份归母净利润同比大增514.49%,显著高于营收增速,其净利润的高速增长主要来自于降本增效。

  财报显示,2024年双林股份毛利率达到18.49%,同比提升了0.95个百分点。其中第一大业务内外饰件及机电部件产品,毛利率提升了2.13个百分点至19.53%,新能源电驱业务毛利率大增8.35个百分点至13.75%,这显著带动了双林股份的盈利表现。

  与此同时,在营收增长的情况下,双林股份期间费用有所减少,期间费用率从2023年的14.04%下降至10.52%。

  今年第一季度,双林股份降本增效趋势仍在持续。其一季度毛利率为21.63%,同比增长0.61个百分点。期间费用率下降至10.36%,同比降低了2.30个百分点。

  业绩复苏的同时,资本市场对双林股份的人形机器人业务有了极高的关注。

  近年来,随着人形机器人的技术突破,人形机器人相关零部件公司也受到资本市场热捧,立项开发行星滚珠丝杠产品的双林股份正是其中之一。

  2022年9月,特斯拉人形机器人Optimus首次亮相。这款机器人全身使用12个线性执行器,采用了“无框电机+倒置滚珠丝杠+行星滚珠丝杠”的机械结构。据介绍,单根行星滚珠丝杠价格近2000元,价值量巨大,引发了行业对人形机器人市场滚珠丝杠产品的高度期待。

  2023年7月,双林股份启动了对滚珠丝杠轴承单元项目的立项,计划从EHB汽车制动用滚珠丝杠轴承到RMB制动用滚珠丝杠、转向用滚珠丝杠轴承、机器人用滚珠丝杠产品逐步进行开发。

  在双林股份看来,公司研发滚珠丝杠产品有着独特优势。人形机器人行星滚珠丝杠产品与公司汽车座椅水平驱动器(HDM),在技术开发上有着同源性,两者结构和传动原理十分相似。公司是国内生产和销售HDM规模最大的企业之一,有着较大领先优势。

  今年3月,双林股份发布国内首款“反向式行星滚珠丝杠”,这比标准滚珠丝杠结构更紧凑、重量更轻,技术难度更大。

  近期在互动平台上,双林股份表示,公司当前已经对接国内两家头部新势力车企,在人形机器人用反向式行星滚柱丝杠项目进行开发,第一批样件订单预计于4月份进行交付。

  与此同时,双林股份也正在通过收购,加强公司在滚珠丝杠领域的竞争力。今年1月,双林股份收购了无锡市科之鑫机械科技有限公司。这是一家专注于研究内外圈磨削技术、内螺纹磨削技术、外螺纹磨削技术,其数控螺纹磨床技术已达到国际领先水平。

  双林股份这笔收购,帮助公司向滚珠丝杠产业链上游环节延伸,进一步强化了公司相关产品一致性及良率,缩短研发周期,使其成为全球先进的掌握反向式丝杠四大核心工艺的企业。

  目前来看,资本市场对双林股份滚珠丝杠业务抱有极高期待,但这一业务目前尚未贡献营收。同时,在滚珠丝杠领域,五洲新春(维权)、北特科技、恒力液压、新剑传动、贝斯特等实力企业都在加速布局,双林股份滚珠丝杠产品能否保持强劲竞争力,帮助其进一步实现业绩突破,尺度商业将持续关注。

华能水电4月24日公告,2025年第一季度实现营业收入53.85亿元,同比增长21.84%;归属于上市公司股东的净利润15.08亿元,同比增长41.56%;基本每股收益0.08元。
